FS#11335 by me: make ARM assembly functions thumb-friendly
...
We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+
Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

YUV Dither: r12 saving was removed but stacked parameter load offset wasn't changed to compensate, resulting in an improperly aligned dither kernel.

Apply some ARMv6 optimisations to YUV blitting. Speeds up mpegplayer on Gigabeat S by ~2% in undithered and ~7.5% in dithered mode.

ARM asm LCD and ATA driver functions: Don't save r12 as it is a scratch reg. Saves a bit of stack and execution time.

Update lcd-as-memframe.S to only rotate YUV data for portrait LCDs (and remove the D2's temporary C implementation). Enable MpegPlayer dithering option for D2.

Dithering option for mpegplayer on gigabeat-f/x and e200. Assembly IDCT for ARm just to make it all work more nicely. Move UI simulator YUV code to its core to adapt it.
