5b369c5cec libs/lbc: remove CHAR_BIT = 16 support 
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.

aa43a0215d mm: fix memory corruption when loop create/exit thread in SMP mode 
Root casue:
when do thread exit, need add free stack operation to mm_delaylist,
but in SMP mode, CPU0 thread1 exit, at this time, CPU1 call malloc
and free mm_delaylist.

Fix:
Divide mm_delaylist for per CPU in SMP mode.

85f0bc591e mm:initialize ensure alignment. 
Broken by 635cfa.

   On an stm32 the heap is formed from
   const uintptr_t g_idle_topstack = HEAP_BASE;
   where HEAP_BASE is &_bss + CONFIG_IDLE_STACKSIZE.

   Both these values are not deterministic. One
   comes from the compiler, the other the system
   configurator.

   a 3 byte bss and 250 byte stack would lead to
   and unaligned address used as the heap to be.

   The compiler used clever `strd r1,r3,[r5,#8]` to
   store 2 values in one memory cycle into the
   heap_impl struct. Resulting in a hardfault.

   Change the amount of bss or the CONFIG_IDLE_STACKSIZE
   could lead to a non-functional NuttX system.

f99f590751 mm: mm_heap: Remove critical section in mm_sem.c 
Summary:
- This commit removes critical section in mm_sem.c which was
  added to stabilize the NuttX SMP kernel in Mar 2018.

Impact:
- SMP only

Testing:
- Tested with ostest with the following configs
 - maix-bit:smp (QEMU), esp32-devkitc:smp (QEMU)
 - sabre-6quad:smp (QEMU), spresense:smp, sim:smp
- Tested with nxplayer with the following configs
 - spresense:wifi_smp, spresense:rndis_smp
