Allocate the device buffer only if the protocol really need to send data.
not all protocols require the driver to prepare additional iob before
sending, especially UDP, each iob reserves l2/l3 header in advance
after prepare write buffer, net device could reuse this entry to send directly

- Also remove the nuttx private shm.h file nuttx/mm/shm.h, which became redundant
- Also remove the gran allocator initialization/release in binfmt since common
vpage allocator is initialized in group_create/group_leave

The dependency should be vice versa; the MM_SHM should depend on the
existence of the virtual memory range allocator.
Create a new CONFIG flag CONFIG_ARCH_VMA_MAPPING, which will define that
there is a virtual memory range allocator. Make MM_SHM select that flag

There is a problem with the original driver reading and writing behavior, refer to the driver of mpu60x0 to make corresponding changes.

Move `SIM_I2CBUS_ID` and `SIM_SPIDEV_NAME` from board to arch.
This allows you not to rely on board configuration.

tg_info is still in use after task_uninit_info(), unifies
lib_stream_* with life cycle of task info to avoid this issue.
