Rafaël Carré adb978a44d Sansa AMS: Various fixes/enhancements for clock frequencies 
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

Thanks to daytona955 on the forums for his help
