fix section error, ARM compiler uses IRAM1.bss to calculate the heap size
fix conflict of _memset between Ameba's library and ARM compiler's library, use standard memset() instead of _memset() in case of ARM compiler
Fix Details: HAL API for loguart is different that UART. Initially we
didnt have support for loguart in the mbed api. These changes have been
made to support the loguart from the mbed api by using the correct HAL
api calls
Based on the Mbed OS website the A3 is connected to "DAC", however there
is no define for DAC. In order to get the Realtek RTL8195AM to even compile
with mbed-os-example-client now, we must have the A3 defined - it is one of
the standard Arduine header pins. Therefore, setting it as NC.
A4-A5 are not connected either, so adding them as "NC" as well.
Realtek will hopefully push a proper fix sooner or later, if there is a
more meaningful define for the A3 pin. They do state however that the
A0-A3 pins are not GPIO capable anyway.

1. move ota region 1 from 0x00b000 to 0x040000
2. move ota region 2 from 0x0c0000 to 0x120000
3. refactor bootloader header as follows:
uint32_t tag;
uint32_t ver;
uint64_t timestamp;
uint32_t size;
uint8_t hash[32];
uint8_t campaign[16];
uint32_t crc32;
where,
a. hash is the sha256 checksum of the payload.
b. crc32 is the crc32 checksum of headers from tag to campaign.
4. Call NVIC_SystemReset for soft reset.

Remove redundant memory regions, and merge multiple RAM regions into one
to solve ielftool zero padding issue.
The side effect is less control over object files placement. It's all up
to linker's best effort.

commit f7bc126 (Re-work Rtl8195AM ticker) tried to address ticker drifting
issue, but in fact broke ticker functionality. This patch adjusts us_ticker
porting to unbreak it, and to fix the following tests:
mbed-os-tests-mbed_drivers-ticker
mbed-os-tests-mbed_drivers-timeout
mbed-os-tests-mbedmicro-rtos-mbed-isr
mbed-os-features-frameworks-utest-tests-unit_tests-minimal_async_scheduler
mbed-os-features-frameworks-utest-tests-unit_tests-case_control_async
mbed-os-features-frameworks-utest-tests-unit_tests-case_async_validate
Changes are:
1. Dont disable timer after every us_ticker interrupt. That basically
breaks ticker functionality.
2. Fine-tune us to tick conversion macro. Previous conversion method
yields 1 tick drift every 2 ms.
3. Remove special placement of ticker objects. No longer necessary.

There was some interesting stuff here.
* ARMC6 treats assembly the same as GNU, but has a different startup
function, so we branch the asm there
* Incorrect discriminant, probably copied from other ports
1. Rearrange SDRAM and SRAM layout. Move timing critical code to SRAM,
and the rest to SDRAM.
2. Add bootloader that's capable of FOTA over mbed cloud.
