[PATCH v7 2/2] ARM : mx35: 3ds-board: add framebuffer device

[Wu Guoxing]

From: wu guoxing <b39297@freescale.com>

This patch adds framebuffer support for freescale mx35 3ds board

Signed-off-by: Wu Guoxing <b39297@freescale.com>
---
Changes since v6:
	1. use the macro for lcd-enable that added in board_mx35_3ds.h
	2. fold mc9s08dz60_lcd_gpio_get into mx35_3ds_lcd_set_power
Changes since v5:
	1. fixed a typo error in fb_modedb[].
Changes since v4:
	1. fixed a typo error in mx35_3ds_lcd_set_power.
Changes since v3:
	1. use a static variable to save the gpio value instead of find
	the gpiochip every time.
	2. add gpio_request after found the gpio.
Changes since v2:
	1. use gpio_set_value_cansleep instead of gpio_set_value
Changes since v1:
	1. use gpio driver for mc9s08dz60
