psxdma: Fix endian issue in gpuInterrupt()
The HW_DMA2_MADR register contains little-endian data, therefore it
must always be accessed through one of the swap macros.
This fixes the slow DMA linked-list walking on big-endian systems.

Add compile-time option to drop psxMemRLUT, psxMemWLUT
Add compile-time option which, if enabled, will replace accesses to
psxMemRLUT and psxMemWLUT with a small inline function psxm().
The reasons behind this change are:
- These were some BIG LUTs. On 32-bit, they would account for 512 KiB of
RAM. On 64-bit, they would account for 1 MiB of RAM. This sounds tiny
by today's standards, but it still is huge for some of the platforms
that PCSX supports.
- Computing the pointer isn't that resource-intensive. Still slower than
reading from a LUT (as long as the LUT entry is in the cache, which it
should be, as the few valid entries are grouped together), but I doubt
that it slows down the interpreter by a lot.
- Even if it does slow down the interpreter a bit, it shouldn't be a
huge deal, given that the interpreter isn't really used nowadays as
the JITs support all the major CPU architectures, and the interpreter
is used mostly for debugging purposes. Besides, the two JITs do not
use these LUTs.
