MIPS: Netlogic: Merge some of XLR/XLP wakup code
Create a common NMI and reset handler in smpboot.S and use this for
both XLR and XLP. In the earlier code, the woken up CPUs would
busy wait until released, switch this to wakeup by NMI.
The initial wakeup code or XLR and XLP are differ since they are
started from different bootloaders (XLP from u-boot and XLR from
netlogic bootloader). But in both platforms the woken up CPUs wait
and are released by sending an NMI.
Add support for starting XLR and XLP in 1/2/4 threads per core.
