target-xtensa: make default CPU depend on target endianness

This makes usable default for -cpu option both for qemu-system-xtensa
and qemu-system-xtensaeb fixing the following error:

$ qemu-system-xtensaeb -M sim
    Unable to find CPU definition

target-xtensa: fix big-endian BBS/BBC implementation

Quote from ISA, 2.1:

For most Xtensa instructions, bit numbering is irrelevant; only the BBC
and BBS instructions assign bit numbers to values on which the processor
operates. The BBC/BBS instructions use big-endian bit ordering (0 is the...

target-xtensa: drop usage of prev_debug_excp_handler

Chains of exception handlers are currently unused feature. Dropping it
to be consistent with target-i386 but it may simplify qom-ifying CPU
in future like for target-i386.

target-xtensa: fix CCOUNT for conditional branches

Taken conditional branches fail to update CCOUNT register because
accumulated ccount_delta is reset during translation of non-taken
branch. To fix it only update CCOUNT once per conditional branch
instruction translation....

target-xtensa: update autorefill TLB entries conditionally

This is to avoid interference of internal QEMU helpers
(cpu_get_phys_page_debug, tb_invalidate_virtual_addr) with guest-visible
TLB state.

Hardware pagetable walking may not be nested. Stop guessing and pass
explicit flag to the get_physical_addr_mmu function that controls page
table lookup.
