Wei-Ning Huang 7eae5a320f stm32f4: clock stm32f412 at 96MHz ...

On stm32f412, AHB prescaler must be 1 in order for stm32f412 to be
clocked at greater than 50MHz. APBX prescaler must be 2 so the clocks
can be in the right range.  When APBX prescaler != 1, it results in 2x
timer clocks on both APB1 and APB2. We added a new
clock_get_timer_freq() function for stm32 to get timer specific clock
frequency so we can return 2x timer clocks when APBX != 1.

Flash latencies also need to be changed when we clock at 96MHz, the
FLASH_ACR_LATENCY defines are moved into the variant-specific switches
so each board can defined latency when setting CPU clocks.

BUG=b:38077127
TEST=`make BOARD=rose -j`, touch performance improved by 2x.
