target-arm: Implement the generic timer
The ARMv7 architecture specifies a 'generic timer' which is implemented
via cp15 registers. Newer kernels will prefer to use this rather than
a devboard-level timer. Implement the generic timer for TCG; for KVM
we will already use the hardware's virtualized timer for this.
