Added GPU reset code (unused because it works as is). Disabled tag RAM and L1 parity checking on ARM11. Don't rely on code overhead at SD card init for the 74 clock pulses. Implemented new cycle accurate delay function.

Corrected OCR register value on SD init to the one from Process9.

Cleanup sdmmc.c/h a bit.

Adjust eMMC clock to be in spec before switching to HS mode.

Optimize SD card poweron for the lowest possible powerup time.

Fixed bugs in sdmmc_send_command(). Partially implemented high speed mode.

[SDMMC] Enable 4 bit mode after switching and always clear fifo.

Disable SD pullup. Set clock back to 16 MHz since the shitty Lexar SDs don't work with 33 MHz.

Update remaining SDMMC clock comments.

Correct comments in sdmmc.c.

Adjust SD init to be in specs.

Remove unneeded reg writes. Set card detect timeout(?) permanently to 0.

Use higher clocks in MMC driver. Needs careful testing!

Move GUI sources in a separate gui folder and hardware sources in hardware folder episode 2.
