OMAP2/3 clockdomains: combine pwrdm, pwrdm_name into union in struct clockdomain

struct clockdomain contains a struct powerdomain *pwrdm and const char
*pwrdm_name.  The pwrdm_name is only used at initialization to look up
the appropriate pwrdm pointer.  Combining these into a union saves
about 100 bytes on 3430SDP.  This patch should not cause any change in
kernel function.

Boot-tested on 3430SDP ES2.
