DRA74x EVM Rev H EVM comes with revision 2.0 silicon.
However, earlier versions of EVM can come with either
revision 1.1 or revision 1.0 of silicon.

The device-tree file is written to support rev 2.0 of
silicon. pdata quirks are used to then override the
settings needed for PG 1.1 silicon.

PG 1.1 silicon has limitations w.r.t frequencies at
which MMC1/2/3 can operate as well as different IOdelay
numbers.

Before we start removing omap3 legacy booting support, let's make n900
DT booting behave the same way for ir-rx51 as the legacy booting does.

For now, we need to pass pdata to the ir-rx51 driver. This means that
the n900 tree can move to using DT based booting without having to carry
all the legacy platform data with it when it gets dropped from the mainline
tree.

Note that the ir-rx51 driver is currently disabled because of the
dependency to !ARCH_MULTIPLATFORM. This will get sorted out later
with the help of drivers/pwm/pwm-omap-dmtimer.c. But first we need
to add chained IRQ support to dmtimer code to avoid introducing new
custom frameworks.

So let's just pass the necessary dmtimer functions to ir-rx51 so we
can get it working in the following patch.

Some omaps are producing imprecise external aborts because we are
wrongly trying to init SRAM for device tree based booting. Only
omap3 is still using the legacy SRAM code, so we need to make it
omap3 specific. Otherwise we can get errors like this on at least
dm814x:

Let's fix the issue by making sure omap_sdrc_init only gets called for
omap3. To do that, we need to have compatible "ti,omap3" in the dts
files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like

have the board files set the irq_trigger explicitly.
