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.
