Mika Westerberg f2eeeae06a OMAP3: serial - fix bug introduced in 
Commit f62349ee97 had side effect that
causes kernel to oops when we are suspending to ram:

This is due the fact that uart_list list was populated in
omap_serial_early_init() and omap_uart_enable_irqs() went through this
list even when serial idle wasn't enabled for all uarts.

This patch moves the code that populates the uart_list and enables uart
clocks into omap_serial_init_port().
