Loyen Wang 0ad5bc50fb arch/arm/src/arm/up_fullcontextrestore.S: When performing stability test, the application would cause kernel crash. When I trace the stack, I find that register R1 has been changed, and its value is the same as register CPSR. In p_fullcontextrestore.S, the restoration of R0 and R1 is not atomic: 'msr cpsr r1 will enable interrupts and the recovery of r0 and r1 may be interrupted and the value or R1 may be changed. Fix is to use a single ldmia to restore R0, R1, and return via R15.

Tiva directories: Fix TM4C129XNCZAD part number in Kconfig and identifiers. Rationale: Fully specify that this is the 212-pin BGA package (ZAD ending) and for consistency with earlier changes to other Tiva TM4C12x part numbers in Kconfig names and identifiers.
