[PATCH 1/3] am335xevm: Add support for musb interface

[Ajay Kumar Gupta]

Adding musb support in am335x EVM board file.

Signed-off-by: Ajay Kumar Gupta <ajay.gupta-l0cyMroinI0@public.gmane.org>
---
These three patches are dependent on my patch set on musb support
for ti81xx recently at [1] and am33xx base port patches from
Vaibhav Hiremath at [2].

[1] http://marc.info/?l=linux-omap&m=131557610318645&w=2
[2] http://marc.info/?l=linux-omap&m=131652916305543&w=2

musb interface on am33xx is exactly same as ti81xx platform and so uses
same glue driver as is.
