In preparation to UART runtime conversion. Remove certain uart specific calls
from pm24xx/34xx files. Remove uart pads from 3430 board file.
These func calls will no more be used with upcoming uart runtime design.
1.) omap_uart_can_sleep :- not needed driver can autosuspend based on usage_count
and autosuspend delay.
2.) omap_uart_prepare_suspend :- can be taken care with driver.
3.) The pad values in 3430 board file are same as the default pad values to be
updated in serial.c file with uart runtime conversion changes.
Avoid structure duplication and use default pads.
