In preparation to UART runtime conversion. Remove certain uart specific calls
from sram_idle path in pm24xx/34xx files.
These func calls will no more be used with upcoming uart runtime design.
1.) Removing console lock holding :- Now can be handled with omap-serial file
itself with appropraite console_enable/disable calls for clk_enable/disable
cases.
2.) omap_uart_can_sleep :- not needed driver can decide based on inactivity.
3.) omap_uart_prepare_suspend :- omap-serial can take care with driver
suspend/resume hooks.
