For CEVA platform CHAR_BIT is 16, and will do lots of extra work
when use IPC.
We will not support this platform anymore, so remove all the b2c operations.

Show a '%p' thing. A nuttx extension is that the '%p' is followed
by an extra set of alphanumeric characters that are extended format
specifiers.
* - 'S' For symbolic direct pointers (or function descriptors) with offset
* - 's' For symbolic direct pointers (or function descriptors) without offset
printf("%ps %pS\n", ptr, ptr) will print:
module_start module_start+0x0/0x62

let the nuttx print out symbolic crash information and
symbolic stack backtraces. This increases the size of the nuttx
somewhat, as all symbols have to be loaded into the nuttx image.

There is a potential problem that can lead to deadlock at
condition wait, if the timeout of watchdog is a very small value
(1 tick ?), the timer interrupt will come before the nxsem_wait()

argv is allocated from stack and then belong to userspace,
so task_info_s is a best location to hold this information.

This commit enables the MCAN driver to function with both rev A and rev B
version of the chip. The version of the chip is selected automtically from
SAM_CHIPID_CIDR register so there is no need to predefined it in the
configuration.
The functonality was tested on rev B version of the chip. The rev A was
not tested since I do not have the functional board but the code remains
the same as in the previous NuttX version so it should not cause any
additional troubles.
The code is co-authored by Miloš Pokorný who wrote the initial transition
to rev B of the chip.
