Subject: [PATCH E 13/14] OMAP2/3 clock: remove clk->owner

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

clk->owner is always NULL, so its existence doesn't serve any useful
function other than bloating the kernel by 992 bytes.  Remove it.

linux-omap source commit is 59ae1e06b177e462d75586d83380f18a7024e77b.
