arm: mach-omap2: am33xx: check VTP before reinitalizing

During a warm reset, the DDR controller will be put into a self refresh
state and will exit self refresh on reset release which will put the
controller in a ready state during bootup.

However we will reinitialize the controller regardless which will
temporarily (~6us) glitch the DDR_RESET line low

Fix this by checking if the VTP controller is already in a ready state
before we initialize the controller unnecessarily.
