IIM:
- Homogenize prg_p naming (the reference manuals are not always self-consistent
for that).
- Add missing SCSx and bank registers.
- Fix the number of banks on i.MX53.
OCOTP:
- Rename iim to ocotp in order to avoid confusion.
- Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the
reference manual.
- Merge the existing spinoff gp1 fuse definition on i.MX6.
- Fix the number of banks on i.MX6.

Some MXC SoCs like the i.MX35 have hosts located at unusual offsets, so prepare
to the introduction of i.MX35 support by defining the ehci-mxc hosts offsets at
SoC level.

imx-regs.h is meant to contain SoC register definitions.
Common SoC funtions should go to sys_proto.h instead.

Clean up i.MX25 imx-regs.h:
- Update mx31 imx-regs.h filename.
- Test for __KERNEL_STRICT_NAMES just in case.
- Define internal RAM size.

Clean up mx25 lowlevel_init:
- Add comments.
- Do not use write32 repeatedly with the same value in order not to increase
code size.
- Make register values configurable.
- Use macro parameters with default values instead of literal constants.
- Use defined macros instead of duplicating code.

Use the standard mxc_get_clock() instead of exporting internal functions and
using literal constant values.

mxc_get_clock(MXC_FEC_CLK) should return the IPG clock, not the AHB clock.
Also, imx_get_fecclk() was correct but reimplemented the calculation of the IPG
clock, so remove the duplicated code.

Define ARCH_MXC for i.MX devices. This is useful to identify features or
behaviors common to all i.MX SoCs.
The i.MX28 is omitted because its architecture is a bit different (like imx/mxc
vs. mxs in Linux).

Each i.MX has its own gpio.h, defining the same structure.
The internal GPIO controller has the same layout
(at least for the register used by u-boot) and can be shared.

types.h must be included in imx-regs.h if one wants to include
imx-regs.h in a board configuration file. That for one's part is
necessary, if one wants to use addresses defined in imx-regs.h.
For example, fsl_esdhc.c needs CONFIG_SYS_FSL_ESDHC_ADDR defined and
a proper thing is to define it with IMX_MMC_SDHCx_BASE in board
configuration file. This patch fixes the build in that case.

Defining CONFIG_FSL_ESDHC brings in a call to get_clocks, so let's
implement get_clocks function. This is how it seems to be implemented
elsewhere.

The serial driver for iMX SOCs is continuosly changed if a
new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port>
defines were used only to find the base address for the selected UART.
Instead of that, move the base address to the board configuration
file and drop all #ifdef from driver.

commit 0edf8b5b2fa0d210ebc4d6da0fd1aceeb7e44e47 breaks

The patch wil fix this issue, generating always asm-offsets.h before
the other targets.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
