[PATCH 3/7] OMAP2+: UART: Remove certain uart calls from sram_idle

[Govindraj.R]

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.
