ARM i.MX31 pcm037: fix erroneous IOMUX GPR setup in pcm037_usb_init()

In commit ad09b59f8bb58c27e3872b41f41beb1b9eb1aeb1 "ARM i.MX31: give
register base addresses a proper MX31_ prefix", the IOMUX GPR setup
to enable USBH2 was replaced with an incorrect source register.
Instead of reading the GPR register, USBOTG HWHOST is used as rmw source,
which contains 0x10020001.
Beside the intended GPR[11] setup ("Enable USBH2 signals on AudioPort 3 and
AudioPort6"), this erroneously also sets
	GPR[28] enable USBOTG loopback
	GPR[17] override DSR_DCE1 with USBOTG_DATA4
	GPR[0]  select FIR DMA requests instead of UART2 DMA

Beside breaking UART2, it probably also broke some UART1 and USB OTG setups.
Fix this and replace the address with the appropriate defines.

ARM: i.MX: Allow disabling SDRAM autodetection

Some boards setup more memory than they actually have. The real memory
size can then be detected later for example by reading a board id.

    ARM: ccmx51: Remove SDRAM size settings

    This patch removes SDRAM memory size setting from board due
    to auto detect last one by ESDCTL.

The board originally configured the SDRAM controller for the
maximum size and detected the usable SDRAM size by reading the
board id. This became broken after switching to automatic SDRAM
size detection by reading back ESDCTL values.

This patch brings back the old behaviour.
