Both the internal and uSD cards are now put into 4 bit widebus mode during initialization except for bootloader.
Add MCI_START_BIT_ERR to MCI_ERROR list and change name to MCI_DATA_ERROR for clarity.
Make appropriate changes to SD error codes.

Correct pow2_* to calculate correct output for input < 0.0 or between 0.0 and 1.0 instead of returning 0. This will change output, but the float version of this codec uses pow(2.0,x) in place of these functions, so this behavior was probably a bug
Replace 64-bit multiply in pow2_* with left or right shift by whole part of input, rounding if shifting right. An ARM-specific optimized version is provided as a C inline function, other targets use a C macro.
Increase constant size of table for pow2 to improve accuracy, also avoid early truncation in linear interpolation of result.
Move constant tables for pow2 and log2 to iram.

key to press in order to select a value.
In anyway, \ButtonRight is not the correct macro to use, as it not necessarily
defined for all targets.

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.

a long, long way to go here, but I just want to get it started.

Some cards need this delay now that we're running at ident speed during this part of the init stage.

* Use consistent name for variables/field names.
* Consistent use of field of structures.
* Simplify draw_polygon().
* Add some helper functions.

Left to add in: a 128x160 backdrop for rockblox to stop errors
when compiling and then to finally enable plugins.

Hopefully the only user visible changes are:
- fm and recording screens go by the statusbar setting (sbs or inbuilt)
- plugins go back to using the theme as they should for menus and lists
- splash screens might get cut a bit... entirely theme and splash dependant.. if there is a problematic one we can look at it later.
- hopefully nothing more than very minor screen flickerings... let me know exactly where they are so they can be fixed
New GUI screen rules:
* Screens assume that the theme (sbs+ui viewport+ maybe background image) are always enabled. They may be disabled on a per display basis, but MUST be re-enabled on exit
* Screens must not be coded in a way that requires a statusbar of any type.. the inbuilt bar will be removed shortly.
ALWAYS RESPECT THE USERS SETTINGS unless the screen requires the full display to fit.
