arm:am33xx: Make dram_init call sdram_init() in some contexts

We have two contexts for booting these platforms.  One is SPL which is
roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main,
board_init_f from SPL, ... then U-Boot loads.  The other is a
memory-mapped XIP case (NOR or QSPI) where we do not run an SPL.  In
this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init,
_main, regular board_init_f.

In the first case s_init will set a valid gd and then be able to call
sdram_init which in many cases will need i2c (which needs a valid gd for
gd->cur_i2c_bus).  In this second case we must (and are able to and
should) defer sdram_init() into dram_init() called by board_init_f as gd
will have been set in _main and cleared in board_init_f.

Flash devices have become more suspectible to bit-flips. Thus stronger

(a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data.
(b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B.

 efficiently.

The {tx,rx}_mac_descrtable fields are aligned to ARCH_DMA_MINALIGN, which could
be 256 or even larger. That means there is a potentially huge hole in the
struct before those fields, so move them to the front where they are better
packed.

Moving them to the front also helps ensure that so long as dw_eth_dev is
properly aligned (which it is since "net/designware: ensure device private data
is DMA aligned.") the {tx,rx}_mac_descrtable will be too, or at least avoids
having to worry too much about compiler specifics.

The {r,t}xbuffs fields also need to be aligned. Previously this was done
implicitly because they immediately followed the descriptor tables. Make this
explicit and also move to the head of the struct.

...I had thought that it was to support some other board which wasn't

but I've just checked and it isn't actually used by any of the boards in

 - parallel NAND flash
 - OneNand flash
 - SDR RAM

Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.

arm: omap3: Fix omap3_overo SPL boot hangup

Patch f33b9bd3
[arm: omap3: Enable clocks for peripherals only if they are used]
breaks SPL booting on Overo. Since some gpio inputs are
read to detect the board revision. But with this patch above, the
clocks to the GPIO subsystems are not enabled per default any more.
The GPIO banks need to be configured specifically now.

OMAP3: overo: eliminate hard-coded partition offsets

The linux kernel is at nand0,3 using the current layout, but is best
accessed through the partition label "linux".  Since CONFIG_CMD_MTDPARTS is
defined the CONFIG_JFFS2 settings are unreferenced; use "setenv partition
rootfs" to set the default mtd partition for jffs2.
