OMAP2/3: PM: remove manual CM_AUTOIDLE bit setting in mach-omap2/pm*xx.c
These CM_AUTOIDLE bits are now set by the clock code via the common PM code in mach-omap2/pm.c. N.B.: The pm24xx.c code that this patch removes didn't ensure that the CM_AUTOIDLE bits were set for several 2430-only modules, such as GPIO5, MDM_INTC, MMCHS1/2, the modem oscillator clock, and USBHS. Similarly, the pm34xx.c code that this patch removes didn't ensure that the CM_AUTOIDLE bits were set for USIM and the AM3517 UART4. Those cases should now be handled.
