In case of muticore CPU, openocd opens one debug port by core for gdb.
Thus add a GDB_PORT_CORE_OFFSET port offset to select the right port
for debugging.

As for debugr, boards like stm32mp157c-dk2 does not have flash memory.
The firmware could be flashed using the operating system (mainly Linux) or
the bootloader (mainly u-boot) of the dual architecture (cortex-A7 on
stm32mp157c-dk2). However in engineering mode (only cortex-M4), the
firmware has to be flashed using jtag once the board is powered up.
The flashr action do this using openocd only.

For multi-arch SoC like STM32MP1, the right target core has
to be selected to avoid debugging the wrong default cpu.
This is done using openocd command 'targets ${OPENOCD_CORE}'.
OPENOCD_CORE has to be set in board Makefile.include file.
In case it is not set, the command just display available targets, thus it
has no effect on already existing boards using openocd.

In case of STM32MP157c-dk2 board, there is no flash available. Thus,
the elf binary has to be flashed directly to SRAM before debugging.
To do so, the DBG_FLAGS variable has to be overrided to load the binary
using 'load' gdb command.
The START_ADDR variable is the entrypoint extracted from the elf binary
using objdump tool.
The do_debug function can now be used as usual.

flashpage currently requires pagewise implementation with an optional
extension for per block writes (flashpage_raw). Most implementations
with flashpage_raw implement the pagewise access via the flashpage_raw
functions. This commit makes the flashpage raw the main access method
and adds an extension feature for the pagewise access.
The functions and defines are renamed to reflect this. The API is also
extended with a dedicated function for erasing a sector.
The number of channels per timer got updated incorrectly in #15368.
Only TIMER1 and higher have four channels. Without this fix, timer
initialization will halt.
