kernel: mask interrupts during callbacks on fx-CG Manager
The fx-CG Manager holds but ignores the CPUOPM.INTMU bit, which means
that we have to mask interrupts as on SH3.

r61524 render-cg: support Prizm and fx-CG Manager
This change adds a new HWCALC model, HWCALC_FXCG_MANAGER, which
identifies Casio's official fx-CG Manager software. Both the Prizm and,
to my surprise, the fx-CG Manager use the old RAM address of 88000000
(P1) and a8000000 (P2) instead of the new fx-CG 50 address of 8c000000
(P1) and ac000000 (P2).

The VRAM is hence adjusted at startup to move hardcoded pointers into
the proper space. Added to the kernel moving the VBR space dynamically
on the Prizm, this allows gint to be fully compatible with these
platforms.

The fx-CG Manager is detected by its product ID made of 0xff.

Also adds a proper interface to the R61524 driver, even though it's not
any more complete than previously, and fixes an oversight where the
HWURAM entry of the kernel data array was no longer computed since the
TLB management change.

As of now, the fx-CG Manager still has a bug regarding return-to-menu
since returning from the main menu doesn't work very well and often
loops. This has been seen occasionally on some Graph 90+E so it's
unlikely to be a platform-specific problem.

t6k11: use the gint array for variant detection
r61524: use true triple buffering by default
display: define DWIDTH and DHEIGHT
display: add C_RGB(r,g,b) (0 ≤ r,g,b ≤ 31) [fxcg50]

dma: only expose API on fxcg50
Currently there seems to be no DMA at all on fx9860g. Further
investigation would be required, because this would be the first major
difference between the SH7305's found in fx9860g and fxcg50 models.

An automated peripheral register discovery strategy might help, but
identifying discovered registers would be non trivial.

Also use the pruning ability of the Makefile to avoid troublesome
ifdef's in the code.

lephe 24fbeab55b core: provide MPU type on unknown platforms
This makes it possible to write application code without specifying the
target machine, which is especially useful for libraries. The first user
of this system is libprof.
