This provides a HAL layer for Modem bearing devices.
Provides a standard interface to upper layer drivers.
Platform providers will be implementing this API under their
specific targets.
As a reference, two implementations are provided under TARGET_C027 (UBLOX)
and TARGET_MTS_DRAGONFLY_F411RE (MultiTech).
targets.json now contains a tag "MODEM" which tells that this target
has a modem and the modem_api is protected by a flag DEVICE_MODEM
(following the DEVICE_SERIAL fashion ).
* Lays down ground for mbed modem_api
* Standardizes pin names relating to modem device for UBLOX C027 and MTS_DRAGONFLY_F411RE
devices
* Ublox modem api is changed to use a standard, platform independent name so that same
api could be used with multiple ubloc modems.
* DCD Polarity macro is added to assist the driver in knowing correct polarity
There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.

Flash programming commands use the top 32 bytes of on-chip RAM. The maximum stack
usage in the user allocated stack space is 128 bytes and it grows downwards.

SystemInit() was called condititionally, but necessary defines were not
set in mbed. Calling SystemInit() unconditional now.
Removed also conditiional calls to legacy CodeRed lib.
Add sleep/deepsleep functions to platform layer which are replacing HAL
functions with the same name, rename existing symbols in HAL layer
to hal_sleep/hal_deepsleep. This way sleep functions
are always available, even if target doesn't implement them, which makes
the code using sleep clearer. It also enables us to make decision on in
which builds (debug/release) the sleep will be enabled.
