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.

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.

TIMER2_7_IRQ is shared among several timer sources, including
us_ticker. Raising TIMER2_7_IRQ pending bit will trigger the timer
interrupt, but the timer interrupt handler will not know which timer
source this interrupt is for. This patch sets timer load value to one
tick and force us_ticker to fire almost "immediately".
TIMER2_7_IRQ is handled through a common interrupt handler, and
is automatically cleared. Therefore, there is no need to clear IRQ.
The underlying timer HAL treats load value as micro-seconds and does
conversion internally. Therefore, simply pass micro-seconds to timer
HAL without converting to tick first.

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.

Fix ARMC6 guard typo introduced in commit 4f3f0cc9cc (Make Realtek link)
While at it, remove redundant ISR_STACK_SIZE assignment for ARMCC.

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
IAR 8.x compiler throws error for emac_interface_t constructor
rtw_emac.cpp@220,0: [Pe1790]: the default constructor of "emac_interface"
cannot be referenced -- it is a deleted function
Error is because new object is created of structure with constant member.
Resolved it by using malloc instead new.
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.

The FlashIAP is supposed to have access to the full application
memory, so the address scope has been changed to encompass
the entire external flash.
The address translation has also been changed to reflect the memory
layout in the documentation:
