gpu: nvgpu: Add hals for router_perfmon_regs_base

gv11b onwards add hals
        get_hwpm_gpcrouter_perfmon_regs_base
        get_hwpm_fbprouter_perfmon_regs_base

And remove the ga10b version of same as that is redundant.

This is preparatory patch to update the gr_gv11b_pri_pmmgpcrouter_addr
and gr_gv11b_pri_pmmfbprouter_addr with the hals
