a98a599cb9 arm/cortex-[a|r]: IRQ Switch return should with shadow SPSR 
The SPSR is used to store the current value of the CPSR when an exception
is taken so that it can be restored after handling the exception.
Each exception handling mode can access its own SPSR.

User mode and System mode do not have an SPSR because they are not
exception handling modes.

    arch/arm: optimize context switch speed

    The current context save implementation saves registers of each task
    to xcp context, which is unnecessary because most of the arm registers are
    already saved in the task stack, this commit replace the xcp context with
    stack context to improve context switching performance and reduce the tcb
    space occupation of tcb instance.

625d230d28 arch/arm/src/stm32f7/stm32_can.c: fix CAN3 receiving 
by fixing filter initialization.

STM32F7 CAN3 works in single peripheral configuration and there is only 14 filter banks: 0-13. Previously not available 14 indexed filter (CAN_NFILTERS/2) was wrongly used for for receiving to FIFO. Now zero indexed filter is correctly used instead.

56e0e6a5ec arch: imx6: Remove sem_t from imx_serial.c 
Summary:
- I noticed that when exiting getprime, DEBUGASSERT happens in
  nxsem_wait()
- Finally, I found that up_putc() uses nxsem_wait()
- This commit fixes this issue by removing the semaphore.
- Also, up_putc() now calls imx_lowputc()

Impact:
- None
