3430ES2 clock: Add several 3430ES2-only clocks

Add several OMAP3430ES2-only clocks:

- DPLL5, which provides clock to onboard USB and USIM modules;

- the Customer Programmable EFUSE;

- MMC3;

- SGX, the graphics module replacing GFX;

- the bandgap temperature sensor;

- USBHOST;

- USB TLL (transceiverless link);

- the Universal Subscriber Identity Module (USIM).

The interface clock for USB TLL is on CM_ICLKEN3, which formerly was
OMAP2430-only; so also convert OMAP2430_CM_ICLKEN3 to CM_ICLKEN3.
