msm8x60_celox: Fix panel init for newer framebuffer drivers

Using pointers (panel_config_gpio & gpio_num) to send this information to the panel driver causes issues (phone doesn't boot & no USB connectivity) when the msm_panel_common_pdata struct in mach/board.h is updated for newer framebuffer drivers.
