Matt Porter a3c3fabb0f arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xx 
In warm reset conditions on OMAP36xx/AM/DM37xx the rom code
incorrectly sets the DPLL4 clock input divider to /6.5 which
is an invalid value unless the input clock is 13MHz. When a JTAG
emulator is attached, a warm reset is necessary after the emulator
gains control of the process. This results in a loss of serial
output due to the invalid DPLL4 settings.

This patch fixes the issue by resetting the DPLL4 clock input
divider to /1 when the input clock is not 13MHz. AM/DM37x TRM
section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only
used when the input clock is 13MHz.
