The SRAM is for use by the MPU. Marking it as such makes it
easier for PM initialization code to locate the SRAM in order to
load a PIE section into it.
Additionally, set the map-exec flag to allow code to be run
from SRAM. This is necessary for suspend/resume.

A recent commit, [PATCH] Fix OMAP EHCI suspend/resume failure
(i693) '354ab856' causes ehci probe to fail on omap3xxx. This
exposed bugs in the ehci_hcd_omap_probe error path causing
an oops.
On the error path, call usb_remove_hcd if usb_add_hcd has been
called, and call usb_put_hcd if
to get that clock from ehci-omap then fails. The solution
is to just change the clock3xxx_data.c for dummy clocks used in the
errata fix to match the dev_id, NULL, used in clock44xx_data.c.
Tested on BB-xM.
