[PATCH] pm2fb: fix big-endian (Sparc) support
A collection of changes that taken together makes the driver work correctly on
big-endian systems, specifically Sparc.
- Remove old PM2FB_BE_APERTURE define and use __BIG_ENDIAN
throughout. PM2FB_BE_APERTURE wasn't defined on Sparc; this
was incorrect.
- Replace colour mode magic numbers with suitable constants,
and tidy colour mode handling. Use BGR not RGB at 24bit on
big-endian.
- Replace aperture magic numbers with constants. Rearrange code to
emphasise second aperture is not used. Add short explanations
of aperture settings for big endian.
- Update comments to note that the driver now works on Sparc.
- Revisit 32bit depth colour offsets and ensure transp is set.
