Subject: [PATCH E 14/14] OMAP clock: rearrange clock.h structure order

From: Russell King <rmk@...-67.arm.linux.org.uk>

... to eliminate unnecessary padding.  We have rather a lot of these
structures, so eliminating unnecessary padding results in a saving of
1488 bytes.

[paul@...an.com: updated against current linux-omap clock tree, now saves
1512 bytes on OMAP3 builds]

linux-omap source commit is 64a423d87fae87608642c28393bb440b45e5e25e.
