we removed "select SCHED_RESUMESCHEDULER",
As SCHED_RESUMESCHEDULER is not a necessary feature in SMP,
turning it on by default may affect performance.

Make channels synchronous (i.e. share the same timebase) with the help
of SAMV7_PWMx_CHy_SYNC defines. All the channels share the same
timebase of channel 0, so this channel must be defined too.

ESP32 SoC use a static allocated array as idle stack. To fit
the existed idle stack allocation, make idle stack allocated
from ebss for the whole esp32 series.

Optimal size of granule is 64B (the dcache line size).
We can use it now as we don't have max. 32 granules limitation anymore.

Implement the bzero function as an alternative to macro expansion.
and support gcc FORTIFY_SOURCE features for nuttx libc
This function will use gcc's function
__builtin_dynamic_object_size and __builtin_object_size
Its function is to obtain the size of the object through compilation,
so as to judge whether there are out-of-bounds operations in commonly used functions.
It should be noted that the option -O2 and above is required to enable this function

Although almost all board support allocating idle stack after ebss,
bl602 have a different memory layout for idle stack. To unify them,
make idle stack allocated from ebss for bl602.

This revises vm_map_region() by accepting unaligned paddr, which is
aligned-down before mapping and in-page offset is then added to vaddr
before returning. It also moves vm_map_region() and vm_unmap_region()
to vm_region.c.

With CONFIG_MMCSD_MULTIBLOCK_LIMIT not set. (No limit)
The DMA driver would overwrite the internal buffer.
By adding CONFIG_ARCH_HAVE_SDIO_PREFLIGHT and
CONFIG_FAT_DMAMEMORY we can insure alignment and
maximize performance using no CONFIG_MMCSD_MULTIBLOCK_LIMIT
