SDRAM init was not working on ES1.0 due to a programming
error. A pointer that was passed by value to a function
was set in function emif_get_device_details(), but the effect
wouldn't be seen in the calling function. The issue came
out while testing for ES1.0 because ES1.0 doesn't have any
SDRAM chips connected to CS1

Convert all OMAP specific functions to use the common API
definitions in include/asm/gpio.h. In the process, made
few additional changes:
- Use -EINVAL consistently. -1 was used in many places.
- Removed one-liner static functions that were used only
once. Replaced the content as necessary.
- Combines implementation of functions omap_get_gpio_dataout()
and omap_get_gpio_datain(). To do so, new static function
_get_gpio_direction() was added.

AM/DM37x is another OMAP3 variant, where the GFX clock has been
boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change.
HW Errata: Due to dependency of TV out clock of 54MHz, it is not
possible to configure GFX to 192MHz. So as per HW errats, the
recommended GFX clock is 200MHz (=CORE_CLK/2).

This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

This change is driven by need of general gpio_* functions,
which as their parameter are accepting the GPIO pin number, NOT
block and pin.
This makes the code alike to omap, and allows for using more
generic frameworks (e.g. software I2C).

Calculate EMIF register values based on AC timing parameters
from the SDRAM datasheet and the DDR frequency rather than
using the hard-coded values.
For a new board the user doen't have to go through the tedious
process of calculating the register values. Instead, just
provide the AC timings from the device data sheet as input
and the driver will automatically calculate the register values.
