ARM: OMAP2+: UART: cleanup + remove uart pm specific API
In preparation to UART runtime conversion remove uart specific calls from pm24xx/34xx files and their definition from serial.c These func calls will no more be used with upcoming uart runtime design. 1.) omap_uart_prepare_suspend :- can be taken care with driver suspend hooks. 2.) omap_uart_enable_irqs :- Used to enable/disable uart irq's in suspend path from PM code, this is removed as same is handled by uart_suspend_port/uart_resume_port in omap-serial driver which will do an port_shutdown on suspend freeing irq and port_startup on resume enabling back irq. 3.) Remove prepare_idle/resume_idle calls used to gate uart clocks. UART clocks can be gated within driver using runtime funcs and be woken up using irq_chaining from omap_prm driver. 4.) Remove console_locking from idle path as clock gating is done withing driver itself with runtime API. Remove is_suspending check used to acquire console_lock.
