Log Message:
Several fixes that help with bringup of non-POSTed Radeon cards.

- Stop preserving sync-disable bits in CRTC_EXT_CNTL
- Unblank path also clears HSYNC_DIS/VSYNC_DIS (for CRTC0)
- Reordered the TMDS transmitter enable after BIOS init
- Skip the FP_SEL_CRTC2 "iBook/XVR-100" restore hack when a BIOS was found
- Program TMDS_PLL_CNTL for internal-TMDS ports
- Skip phantom ports when building the CRTC list (for single-port RV100)
- Pixel clock ungating where appropriate

Tested on RV100 and RV280 with RADEONFB_BIOS_INIT.
