X-Git-Tag: v3.6-rc1~16^2~11^2^2~8

OMAPDSS: RFBI: Configure dss_lcd_mgr_config struct with lcd manager parameters

Create a dss_lcd_mgr_config struct instance in RFBI. Fill up all the parameters
of the struct with configurations held by the panel, and the configurations
required by RFBI.

Use these to write to the DISPC registers. These direct register writes would be
later replaced by a function which applies the configuration using the shadow
register programming model.

Create function rfbi_config_lcd_manager() which fills up the mgr_config
parameters and writes to the DISPC regs.
