arm: mxs: Enable booting of mx28 without battery

Section 4.1.2 of Freescale Application Note AN4199 describes the
configuration required to operate the mx28 from a 5V source without a
battery.

This patch changes the behaviour of the dropout control of the DC-DC
converter (refer to section 11.12.9 of the mx28 Application Processor
Reference Manual - Document Number: MCIMX28RM, Rev 2, 08/2013) to the
following:
- Always use 4P2 Linear Regulator if CONFIG_SYS_MXS_VDD5V_ONLY is defined
- Switch between 4P2 Linear Regulator and Battery, using whichever has
the highest voltage if CONFIG_SYS_MXS_VDD5V_ONLY isnot set (this is
the same as the pre-patch behaviour)

It is difficult to track down fail to boot issues in the mxs SPL.
Implement the following to make it easier:
- Add debug outputs to allow tracing of SPL progress in order to track
where failure to boot occurs. DEUBUG and CONFIG_SPL_SERIAL_SUPPORT must
be defined to enable debug output in SPL
- Add TODO comments where it is not clear if the code is doing what it
is meant to be doing, even tough the board boots properly (these comments
refer to existing code, not to any code added by this patch)

mx25: Fix boot hang by avoiding vector relocation

CPU: Freescale i.MX25 rev1.2 at 399 MHz
Reset cause: WDOG
Board: MX25PDK
I2C: ready
DRAM: 64 MiB
(hangs)

Add a specific relocate_vectors macro that skips the vector relocation, as the
i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and
(0x00000000) maps to ROM.

This allows mx25 to boot again.

imx: fix exception vectors relocation in imx27

Commit 3ff46cc4 fixed exception vectors setting in
the general ARM case, by either copying the exception
and indirect vector tables to normal (0x00000000) or
high (0xFFFF0000) vectors address, or setting VBAR to
U-Boot's base if applicable.

i.MX27 SoC is ARM926E-JS, thus has only normal and
high options, but does not provide RAM at 0xFFFF0000
and has only ROM at 0x00000000; it is therefore not
possible to move or change its exception vectors.

Besides, i.MX27 ROM code does provide an indirect
vectors table but at a non-standard address and with
the reset and reserved vectors missing.

Turn the current vector relocation code into a weak
routine called after relocate_code from crt0, and add
strong version for i.MX27.
