phb3/capi: Initialize capp regs with field values.
FLUSH_SUE_STATE_MAP change fixes a problem with recovery. We were using an old
lab value that marked PTE entries in a shared state. After recovery, PTE
entries were getting flushed out to memory with an SUE, resulting in a machine
check. The new value means PTE entries are dropped on recovery.
For, APC_MASTER_PB_CTRL spec says to use initfile value and bit 3 should be
set. Initfile missing bit 3 so do a RMW. Bit 3 enables CAPP combined
response.
CAPP_EPOCH_TIMER_CTRL enables epoch timers and the recovery timer when recovery
is enabled. Also relax epoch timer period mask due to a bug.
TRANSPORT_CONTROL reg set bit 37 - rfs_benign_ptr_data in addition to spec
value. Should be set in initifile in future.
Rename APC_MASTER_CONFIG to APC_MASTER_CAPI_CTRL to match workbook name.
