Remove HAL_Init and related code from SystemInit and move it to
mbed_sdk_init. The function SystemInit is called early in the boot
sequence before RAM is initialized or the VTOR is setup, so it should
not be used to perform the HAL initialization.
This fixes crashes due the vector table being used before it has been
relocated.
1. Add startup code and linker script for IAR and
GCC_ARM compilers.
2. Enable IAR and GCC_ARM compilers in targets.json.

Based on lwip_ethernetif.c skeleton file,
use init, receive and transfer
functionality of SMSC9220 Ethernet driver
for the lightweight IP stack.
Receive mechanism is interrupt driven.
HW buffer sizes:
Tx = 4608 bytes (MTU)
Rx = 10560 bytes

- Creates new target in targets.json
- Creates device specific files under ARM_SSG/CM3DS_MPS2 directory
- Driver layer files under CM3DS_MPS2 are based on Beid target
- Device specific files under CM3DS_MPS2/device are based on CMSIS_5 and Beetle

Define CMSIS_VECTAB_VIRTUAL for the M0 targets which have a
corresponding driver. The only M0 target missing this is the LPC4330_M0
which is not part of the 2 or 5 release.
Restore cmsis_nvic (cmsis_nvic.c and cmsis_nvic.h) files for the
implementations which use a mechanism other than the VTOR to set
interrupts. These are vendor specific and were done for M0 devices
which do not have a VTOR.
Note - There were two cmsis_nvic files which did not use the VTOR that
which not restored in this patch. This is because these targets were
not M0 devices and could use the new unified implementation instead.
These files are:
targets\TARGET_ARM_SSG\TARGET_MPS2\TARGET_MPS2_M0P\device\cmsis_nvic.c
targets\TARGET_ONSEMI\TARGET_NCS36510\device\cmsis_nvic.c
Note - cmsis_nvic.c and cmsis_nvic.h were initial removed in
(and restored from) the commit:

"CMSIS5: Replace target defined NVIC_Set/GetVector with CMSIS implementation"
The use of mktime was causing a fault when called in interrupt handler because on GCC it lock the mutex protecting the environment, To overcome this issue, this patch add dedicated routine to convert a time_t into a tm and vice versa.
In the process mktime has been optimized and is now an order of magnitude faster than the routines present in the C library.
The Ameba RTC driver converts time_t to
second/minute/hour/day/month/year in rtc_write and back to time_t in
rtc_read. Replace this with an implementation which uses time_t
directly.
