phb4: Dump CAPP error registers when it asserts link down
This patch introduces a new function phb4_dump_app_err_regs() that
dumps CAPP error registers in case the PEC nestfir register indicates
that the fence was due to a CAPP error (BIT-24).
Contents of these registers are helpful in diagnosing CAPP
issues. Registers that are dumped in phb4_dump_app_err_regs() are:
* CAPP FIR Register
* CAPP APC Master Error Report Register
* CAPP Snoop Error Report Register
* CAPP Transport Error Report Register
* CAPP TLBI Error Report Register
* CAPP Error Status and Control Register
