[media] davinci vpbe: add VENC block changes to enable dm365 and dm355 

This patch implements necessary changes for enabling  dm365 and
dm355 hardware for vpbe. The patch contains additional HD mode
support for dm365 (720p60, 1080i30) and appropriate register
modifications based on version numbers.

VPBE_VERSION_2 = dm365 specific
VPBE_VERSION_3 = dm355 specific
