OMAP: DSS2: DSI: enable scp clock in dsi_dump_regs()
OMAP4 requires SCP clocks enabled to access DSI PLL registers and DSI COMPLEXIO registers. Enable scp clock before accessing the registers and disable it before exiting dsi_dump_regs(). Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
