target-lm32/microblaze: Drop second CPU{LM32, MB}State typedef

Commit 9b9a970a23625de4ae6b7461906a9a0d98d3ca95
(target-lm32/microblaze: Typedef struct CPU{MB,LM32}State)
introduced necessary typedefs for cpu_mmu_index() and mmu.h
respectively.

On some GCC versions this leads to "error: redefinition of typedef"....

Rename cpu_reset() to cpu_state_reset()

Frees the identifier cpu_reset for QOM CPUs (manual rename).

Don't hide the parameter type behind explicit casts, use static
functions with strongly typed argument to indirect.
