OMAP3 clock: introduce DPLL4 Jtype

Browse Source 
DPLL4 for 3630 introduces a changed block called j type dpll, requiring
special divisor bits and additional reg fields. To allow for silicons to
use this, this is introduced as a flag and is enabled for 3630 silicon.
OMAP4 also has j type dpll for usb.

Tested with 3630 ZOOM3 and OMAP3430 ZOOM2
