qemu-log: add log category for MMU info
Running barebox on qemu-system-mips* with '-d unimp' overloads
stderr by very very many mips_cpu_handle_mmu_fault() messages:
mips_cpu_handle_mmu_fault address=b80003fd ret 0 physical 00000000180003fd prot 3
mips_cpu_handle_mmu_fault address=a0800884 ret 0 physical 0000000000800884 prot 3
mips_cpu_handle_mmu_fault pc a080cd80 ad b80003fd rw 0 mmu_idx 0
So it's very difficult to find LOG_UNIMP message.
The mips_cpu_handle_mmu_fault() messages appear on enabling ANY
logging! It's not very handy.
Adding separate log category for *_cpu_handle_mmu_fault()
logging fixes the problem.
