The blue bars I previously had with this way are fixed by blocking DBOP output while reading buttons from GPIO.
We reached the maximum fps even at unboosted now (100.0 fps at lcd_update(), DBOP can't do more). Optimisation to YUV stuff is still possible though.
The e200v2 scrollwheel is very improved due to the this and the previous speedup since the chance of getting the wheel read blocked is greatly decreased with faster updates.

Unaligned (to 4byte boundary) and odd (where the amount of data is not an integer multiple of 32bit) are still supported. Even those still have a speedup of >2.

Those two drivers were so similar, merging them is worth a few more #ifdefs.

- cache IRAM and DRAM
- map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize
- tweak delays in Fuze button code
- tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on)

*Correct/update some comments
*Make BUTTON_REPEAT generation more relable (do it like the e200v2, but with a shorter repeat intervall)
*adjust button_delay
*remove unecessary wait for fifo empty (no lcd function returns with fifo not empty)

Fix CGU_DBOP setting
Set PCLK to the exact frequency (62MHz, not the maximal frequency)
Use a better comment for CLK_DIV macro
Use preprocessor safety checks for clock divider sizes to avoid future mistakes (not for SD_IDENT frequency since that check is handled by mci_set_clock_divider)
Use maximal IDE frequency of 66MHz (like OF), not 90MHz like written in AS3525 datasheet. The IDE chip is somehow linked to internal storage, and a too high frequency could affect the storage driver.
Use the same DBOP frequency of 32MHz for all models (like OF, verified clip, fuze, e200v2 and m200v4), compromise between performance and battery life could be added in the future for each target
Performance increase on Sansa Fuze with DBOP freq. set to 64MHz: +12% fps for lcd_update, +1% fps for yuv

a) lcd_enabled() is now lcd_active(), and is available for HAVE_LCD_SLEEP only targets (e.g. ipod video) too. It was depandent on HAVE_LCD_ENALE only before
b) rename the hook accordingly, and implement the hook for other other targets too (e.g. the clip [the only mono target with lcd_enable/lcd_sleep yet, so the code is still in the lcd driver], ipod, fuze, c200)

1) fix driver from reading invalid home button while lcd updates (use old value then)
2) put in a 1s delay for power button reading after releasing hold
3) revert r20028, I thought it wasn't needed, since I didn't update the bootloader
4) enable hold for the bootloader (even though not really needed, but is consistent with other targets)
5) let button_dbop return DBOP_DIN, and do the reading in button_read_device
6) various cleanups

Reorder system_init() to initialize peripherals not only in bootloader
Use a 65MHz PCLK (and memclk) which will be needed for realtime decoding

Fix lcd drivers which stopped working after changing the PLL.
Move set_cpu_frequency() to a place where it is actually used.
Remove enable_irq() call already done by the bootloader

Use a 24MHz peripheral clock instead of 64MHz for battery life
