c6a51bab17 bx50v3: Use imx_ddr_size() for calculating the DDR size
imx_ddr_size() can be used to calculate the DDR size in runtime.

By using this function we no longer need to define PHYS_SDRAM_SIZE.

8d293f49b4 board: ge: bx50v3: Fix to meet LVDS display power on timing
On a reset/reboot, the display power needs to be off for atleast 500ms
before turning it back on. So add a delay to the boot process to meet
the display timing requirement.

494d43ec35 board: ge: bx50v3: Setup LDB_DI_CLK source
To generate accurate pixel clocks required by the displays we need to
set the ldb_di_clk source on bx50v3 to PLL3 and b850v3 to PLL5. Since
PLL5 is disabled on reset, we need to enable PLL5.

de708da0e8 board: ge: bx50v3: Split display setup function
B450v3/B650v3 uses single channel LVDS and does not support HDMI.
B850v3 uses dual channel LVDS and supports HDMI. Hence split the display
setup into two different functions.

7d0b8cfeaa board: ge: bx50v3: Disable unused pins
Certain pins are not used on the i.MX6, and should have a neutral
pad configuration in order to reduce electrical interference on
the board. This commit defines these pins with a default value
rather than relying on the system defaults.
