This gets rid of LCD glitches on Sansa Fuze, and now LCD transfers can
get interrupted by button reading

This patch changes all references/assumptions of PCLK to IDE_CLK for the internal pl180 controller.
Lower the AS3525_IDE_FREQ to 50 MHz in order to be able to divide by 2 for 25 MHz on the internal SD card.
Adjust the code in debug-as3525.c to account for the change and the frequencies reported should be correct.
Add some #if defined(HAVE_MULTIDRIVE) conditionals to cut out the code dealing with uSD for the clip.
Isolate the write delay needed for low frequency writes to only run for standard speed uSD cards. That is the only case for an MCICLK at 15.5 MHz.
Internal cards run at 25 MHz, HS uSD at 31 MHz, and standard speed uSD cards at 15.5 MHz.

If the controllers were already enabled there was a chance we could try to read the MCI_CLOCK registers while the cards were buffering and then disable the controllers prematurely.
I guess funman knows and sees all!! Thanks funman.

Because we turn off the clocks to the SD controllers between disk accesses we were unable to read the MCI_CLOCK registers until there was a disk access. Now we can read them immediately.

Adjust SD timeouts accordingly.
Adjust code in debug-as3525.c to display correct frequencies on system/debug/View disk info page.

of 400 khz Ident freq. Also misc formatting changes.
Displaying the 400 khz ident frequency for the SD and uSD cards was not really
useful information. This change displays the MCICLK frequency that we are
running the cards at. The page now displays 0MHz until a card access and then
will displays the set frequency and the actual frequency. The uSD display is
now only displayed for those players with a uSD

Lower CVDD core voltage to 1.10 volts when the frequency is less than 200 MHz.

- Indentation fix
- Put braces around _DEBUG_PRINTF macro
- read_cp15() is only 1 instruction so inline it, and it doesn't access memory

Don't read the buttons from GPIOC but from DBOP_DIN (all directional buttons + select)
Still missing hold, rec, volume up and volume down
Read microsd
Tuner is a si4700 but seems to suffer from the same problem than e200v2
Sound works
TODO: missing buttons, lcd yuv, test lcd performance (the c200v1 lcd performance has decreased since r21321 : needs to be investigated)

With a few modifications by me:
Return 0MHz for PLL disabled (PLLB)
Mention if i2si and i2so are on or off
Simplify scrolling (for small & large displays)

Implement some of the new functions
Use as3514 rtc
Add AS3525 case in rolo.c
Copy card_get_info_target() from ata-sd-pp.c , and use the correct 32bits words order
