We defined PHYS_DRAM_1 to 0x80000000 (start of DRAM) and then used this
for CONFIG_SYS_SDRAM_BASE.  But then we kept on referencing PHYS_DRAM_1
in other places.  Change to directly setting CONFIG_SYS_DRAM_BASE and
then using that name in code.

The location of valid scratch space is dependent on SoC, so move that
there.  On OMAP4+ we continue to use SRAM_SCRATCH_SPACE_ADDR.  On
am33xx/ti814x we want to use what the ROM defines as "public stack"
which is the area after our defined download image space.  Correct the
comment about and location of CONFIG_SPL_TEXT_BASE.

Prior to Sricharan's cleanup of the boot parameter saving code, we
did not make use of NON_SECURE_SRAM_START on am33xx, so it wasn't a
problem that the address was pointing to the middle of our running SPL.
Correct to point to the base location of the download image area.
Increase CONFIG_SPL_TEXT_BASE to account for this scratch area being
used.  As part of correcting these tests, make use of the fact that
we've always been placing our stack outside of the download image area
(which is fine, once the downloaded image is run, ROM is gone) so
correct the max size test to be the ROM defined top of the download area
to where we link/load at.

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards.  We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/.  We leave
the NAND one in-place as we plan to replace it later in this series.

We use common/spl to avoid linker problems with respect to merging
constant strings in objects.   Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

Make the lowlevel_init function that these platforms have which just
sets up the stack and calls a C function available to all armv7
platforms.  As part of this we change some of the macros that are used
to be more clear.  Previously (except for am335x evm) we had been
setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are
equivalent to simply referencing NON_SECURE_SRAM_END.  On am335x evm we
should have been doing this initially and do now.
