hw/hppa: Make number of TLB and BTLB entries configurable
Until now the TLB size was fixed at 256 entries. To allow operating
systems to utilize more TLB entries in the future, we need to tell
firmware how many TLB entries we actually support in the emulation.
Firmware then reports this to the operating system via the
PDC_CACHE_INFO call.
This patch simply does the preparation to allow more TLB entries.
