Fix handling of the Cirrus Logic GD5434 chip. Distinguish this chip from the GD5430. It allows detecting memory size for both models correctly.

A memory clock (MCLK) is set at various places. Move the setting into one place. Set the MCLK only for Zorro cards as the x86 cards should be initialized by BIOS. Improve handling of the GD5434 (SD64). Kill one annoying debug output "virtual offset: ...".

- The Laguna GD5465 (AGP) has one register more than non-AGP chips. Recognize the AGP version and write a tile control register only on the AGP version. Tested only on an AGP card. - Bump up RAMDAC frequencies after X11 code. This allow to drive a flat panel resolution 1680x1050 at 16bpp from the 4MB card. - Fix screen start address overflow bits on Laguna cards (CRT1D register). - Fix exit path in the cirrusfb_pci_register() in case of error.

Break cirrusfb_decode_var() function into two parts: cirrusfb_check_pixclock() which can be called from the cirrusfb_check_var() aand merge rest into the cirrusfb_set_par_foo(). This allows rejecting modes with too high pixclock before before any change to hardware state (and a console is messed up). Also, fix RGB field's lengths for 8bpp modes to correct ones so X11 works with fbdev driver with cirrusfb. Kill some redundant function calls or register loads.

Various improvements to the code: - kill a structure with only one field: multiplexing and use the field directly - move the cirrusfb_ops structure down the file to kill forward declarations - move cirrusfb_init() to kill forward declaration - kill register loads done already in the init_vgachip() - kill assigments done by higher layer in the cirrusfb_pan_display() - do not overwrite line pitch bit in the CL_CRT1D register - kill btype variables if they were used only once or twice - add cpu_relax() in the busy waiting loop The fix to the CL_CRT1D register handling makess the 1024x768 32bpp mode work.

The Laguna chipsets use special registers which are available through the mmio area. The cirrusfb driver does not use memory mapped registers for the PCI cards. Add the memory mapped area for Laguna chipsets and add basic usage of the special Laguna registers after SVGALIB code. This gives readable console at 16bpp on the GD-5465 (Laguna AGP).

A memory clock value (MCLK) is changed to a minimum required by a current mode bandwidth. This usually lowers the MCLK to its minimum (50 MHz) thus decreasing the card performance. Just leave the MCLK value set by card BIOS. The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a jitter on the screen. A countermeasure is to use the MCLK as pixclock source instead of a VCLK. The patch implements this as well.
