The mx5 lowlevel_init.S contains board-specific code based on the reference
design. Let's keep it since it avoids creating new lowlevel_init files and it
may be used by many boards. But add a config to make it optional in order not to
cause issues on boards not following this part of the reference design.

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.

efikamx board, for example, does use a MC13892 PMIC, but the RTC selection is currently made as:

This magic constant with zero documentation, when it's last 8 bits are set to
0x45, configures correctly the PERCLK dividers. Therefore the I2C operates
correctly when divider computed from PERCLK.
Note: This constant is written to CBCDR register in
arch/arm/cpu/armv7/mx5/lowlevel_init.S, but it's written only once. The register
is accessed three more times in the file, with different values written to it
each time.

For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().
With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway. So don't keep this relict any
longer.

This patch is to fix build breakage and support new relocation
scheme for mx51evk.
- Correct IRAM base address and add size definition
The IRAM starts from 0x1FFE0000 on final revsion i.mx51 than
0x1FFE8000 which is for older revision.
- Include imx-regs.h in mx51evk.h
Definitions like CSD0_BASE_ADDR and IRAM_BASE_ADDR can be
referred to.
- Define CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE
They are used to define init RAM layout.
- Remove comment for CONFIG_SYS_GBL_DATA_SIZE which has been
buried by Wolfgang's commit below

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

The handling of the SPI_CPOL bit inside the SPI
driver was wrong. As reported by the manual,
the meaning of the SSPOL inside the
configuration register is the same as reported
by SPI specification (0 if low in idle, 1 is high
on idle). The driver inverts this logic.
Because this patch sets the logic as specified, it is required
to clear the CPOL bit in the configuration file to adapt
to the correct logic.
