[PATCH] Atyfb on Mach64 GX or Atari

Here's the latest incarnation of the atyfb fix for Mach64 GX (compiles with
warnings and cannot work) and Atari.
There's only one chance since the last version I sent in September: the probing
for the crystal frequency is now done for all chips with integrated clock
generator.
---snip---
Atyfb: Make Mach64 GX and Atari support build:
- ram_resv[] is needed for Mach64 GX, too.
- Move declaration of v, since it's used for generic LCD only.
- aty_ld_pll() used to be global, but now it's defined for Mach64 CT only,
causing a link failure if you don't enable Mach64 CT support. Hence make it
Mach64 CT dependant.
- Move declaration of pll_ref_div, since it's used for Mach64 CT only.
- Probe the crystal for all chips with integrated clock generator, not only
for chips with a GTB-style DSP.
- Kill warnings when ioremap()ing in the Atari case.
- Add missing xres parameter to Mach64 GX aty_var_to_pll_*() routines.
Most of these problems show up on other platforms (e.g. PPC) if you enable
support for Mach64 GX.

when I'm talking to journalists I just say "programmer" or something like that.
