* arch/arm/srch/stm32/stm32_otgfshost.c: Replace timeout handling; use
system tick instead of frame counter. The frame counter gets rset to
zero at 0x3fff making it error prone.
* arch/arm/src/stm32/stm32f20xx_rcc.c and stm32f40xx_rcc.c: Added option
CONFIG_STM32_FLASH_PREFETCH. FLASH prefetch will now only be enabled
if this option is selected.
