Some features can be configured by the companion I2C chips,
which may not be available at the probe time. Fix the issue
by returning -EPROBE_DEFER when the MMC controller slots
are not configured.
While at it, let's also add minimal device tree support so
omap24xx platforms can use this driver without legacy mode
since we claim to support device tree for mach-omap2 based
systems.
Although adding the minimal device tree support is not strictly
a fix, it does remove one of the last blockers for dropping a
bunch of legacy platform data for mach-omap2.

Beagle (rev. C4) and Beagle-XM (all revs) need VAUX2 1.8V supply
for the USB PHY.
As the generic PHY driver can't handle more than one supply
at the moment, we configure this supply to be always on.
This will cause a very small power impact if the USB host subsystem
is not in use, about 76.86 micro-W + LDO power.
Older Beagle boards (prior to C4) don't have VAUX2 connected anywhere,
so there won't be any functional impact on those boards other than
some additional LDO power consumption.

Enabling of Posted mode is seen to cause problems on dmtimer modules on AM33xx
(much like other OMAPs). Reference discussions on forums [1] [2]. Earlier
patch solving this on other OMAPs [3].
For OMAP SoCs with this errata, the fix has been to not enable Posted mode.
However, on some SoCs (atleast AM33xx) which carry this errata, Posted mode
is enabled on reset. So we not only need to ignore enabling of the POSTED bit
when the timer is requested, but also disable Posted mode if errata is present.

The emulated bridge does not support interrupts, so it should return the
value 0 for Interrupt Line and Interrupt Pin. This indicates that
interrupts are not supported.
Since Max_Lat and Min_Gnt are also in the same 32-bit word, we return
0 for them, which means "do not care."
This corrects an error message from the kernel:
