Core configuration register IFU_BRUB_RESERVE has to be setup to handle
a silicon errata which can result in a CPU hang.

Since we now use r4k cache code for Netlogic XLP, it is
better to split L1 icache among the active threads, so that
threads won't step on each other while flushing icache.
The L1 dcache is already split among the threads in the core.

Update for core intialization code. Initialize status register
after receiving NMI for CPU wakeup. Add the low level L1D flush
code before enabling threads in core.
Also convert the ehb to _ehb so that it works under more GCC
versions.

- Update common files to support XLP.
- Add arch/mips/include/asm/netlogic/xlp-hal for register definitions
and access macros
- Add arch/mips/netlogic/xlp/ for XLP specific files.
