ENGR00132759 MX53: use 32K CLK as GPT source
MT29F16G08MAA NAND flash was failed on MX53 ARD/RevB
board, but it's fine in RevA board. After check, it's
found that udelay is not accurate on MX53 ARD/RevB
board because GPT uses IPG peripheral clock and assume it
is 50MHZ. However IPG peripheral clock is not 50MHZ in
MX53 ARD/RevB board. So it causes udelay is not accurate.
This patch changes GPT clk source as 32K to make udelay
accurate.
