Billy Kozak feec05cdf2 CC26xx - fix misuse of len variable in read_frame
read_frame was misuing the packet length in the following ways:
- returning non-zero even if buf_len is too short for the packet
- truncating the length to buf_len if len is too long then using the
  truncated (i.e. wrong) length to index into the buffer
- memcpying too many bytes (used buf_len instead of real length)

This commit fixes all of this and adds some code to report
on packet length errors (to match with cc2538 driver).

Billy Kozak ceb24f656e Improved style of read_frame
- moved variable declaration to top of function in accordance with the
  Contiki style guide
- made function flatter, reduced nesting to improve readability

Billy Kozak 547f8e7aaa Fixed race condition with rf cpu in read_frame
Fixed a race condition that could occur in read_frame because the
dataEntry is set to PENDING before we are finished reading from it.

Billy Kozak 35919f6836 CC26xx - Enable RX_NOK on DEBUG builds
Enabled the RX_NOK interrupt, if DEBUG or CC26XX_DEBUG_CRC are set
true, for the purpose of monitoring packets with bad CRC

Billy Kozak 99d74e949f CC26xx autoflush bad crc packets
Setting bAutoFlushCrc=1 so that the radio co-processor will
automatically drop packets with bad crc.

Billy Kozak b7565f3930 turned on correlator in radio packet filter
Enabling this option seems to greatly improve transciever performance with
Contikimac. This seems to happen because Contikimac CCAs are much less likely
to detect false positives (thus screwing up the CCA sequence).

George Oikonomou 07272b7cd6 Improve UART power-cycling logic:
* Only enable TX by default.
* Add some magic for RX handling. When an input handler is registered:
  * Automatically enable RX-related and interrupts
  * Automatically lock the SERIAL PD on under all power modes
  * Automatically enable the UART clock under sleep and deep sleep
  * Automatically undo all of the above when the input handler becomes NULL
  * As a result, modules / examples that need UART RX no longer need to clock the UART and manipulate the SERIAL PD. They simply have to specify an input handler
* Don't automatically power on the UART whenever the CM3 is active
* Before accessing the UART, make sure it is powered and clocked
* Avoid falling edge glitches
* Fix garbage characters / Explicitly wait for UART TX to complete

George Oikonomou 34f52ed08e Improve the LPM module:
* Implement new style of PD locks
* Use our own shutdown sequence rather than the one provided by cc26xxware
* Shutdown from within the interrupt that requested it. This allows shutdown to take place even if the code is stuck in a loop somewhere else
* Improve DCDC/GLDO/uLDO switching logic
* Explicitly handle oscillators and retentions

George Oikonomou 421fbfae25 Change the LPM locks API:
Instead of using a separate data structure to request that a PD remain powered during deep sleep,
we do the same within the main LPM data structure through an additional field.

This allows us to maintain only one linked list of LPM modules and overall improves code clarity

Benoît Thébaudeau 19fd7a3551 Use additive offsets
OR-ing an offset to a base address instead of adding it is dangerous
because it can only work if the base address is aligned enough for the
offset.

Moreover, if the base address or the offset has a value unknown at
compile time, then the assembly instructions dedicated to 'base +
offset' addressing on most CPUs can't be emitted by the compiler because
this would require the alignment of the base address against the offset
to be known in order to optimize 'base | offset' into 'base + offset'.
In that case, the compiler has to emit more instructions in order to
compute 'base | offset' on most CPUs, e.g. on ARM, which means larger
binary size and slower execution.

Hence, replace all occurrences of 'base | offset' with 'base + offset'.
This must become a coding rule.

Here are the results for the cc2538-demo example:
 - Compilation of uart_init():
    * before:
        REG(regs->base | UART_CC) = 0;
        200b78:	f446 637c 	orr.w	r3, r6, #4032	; 0xfc0
        200b7c:	f043 0308 	orr.w	r3, r3, #8
        200b80:	2200      	movs	r2, #0
        200b82:	601a      	str	r2, [r3, #0]

    * now:
        REG(regs->base + UART_CC) = 0;
        200b7a:	2300      	movs	r3, #0
        200b7c:	f8c4 3fc8 	str.w	r3, [r4, #4040]	; 0xfc8

 - Size of the .text section:
