1. using armv6-m arm_irq();
2. simplify the interrupt number get process;
3. To improve the performance, move common exception code to ram_code.

Summary:
- Because a context switch issue still exists with FPU,
it should be enabled only if EXPERIMENTAL=y
Impact:
- None
Testing:
- Tested with ostest

1. add pulse count support for pwm0;
2. add more detailed config for pwm;
3. pwm configuration and start process optimize;
4. tlsr82/Kconfig format;

Summary:
- The configuration is no longer needed because Kconfig has
been fixed in the previous commit
Impact:
- None
Testing:
- Tested with QEMU

Summary:
- TIVA_WITH_QEMU is used to run the NuttX with QEMU
- The configuration should not depend on TIVA_ETHERNET
- This commit fixes this issue

_xtensa_sig_trampoline is returned to after a context switch and not called
by the usual Window call instructions (call4, call8 and call12),
thus does not need the entry instruction. Furthermore, the ENTRY instruction
in this case is messing up the backtrace as it creates an extra frame.

Do not call strlen() here. Old implementation iterated
over string twice, if searched for position was at the
beginning. This commit changes strrchr() to scan string
only once, regardless of input.

Summary:
- In case of SMP and ADDRENV, allocate current group for each cpu
- g_pid_current holds pid of the group and uses for addrenv switching
- allocate g_group_current for each cpu in stead of g_pid_current
- g_group_current is the array that pointed to the current task_group_s struct
Impact:
- ADDRENV=y and SMP=y

- sabre-6quad:smp w/ qemu
