block: row: fix sysfs functions - idle_time conversion

idle_time was updated to be stored in msec instead of jiffies.
So there is no need to convert the value when reading from user or
displaying the value to him.

OMAP4: SMC: Fix compiler warnings in omap4-common.c

arch/arm/mach-omap2/omap4-common.c:40: warning: 'l4_secure_clkdm'
	defined but not used

If SMC is defined, we use a different omap4_secure_dispatcher and
l4_secure_clkdm was being defined but not used in omap4-common.c. The
solution here is to wrap the declaration in same #ifdef as
omap4_secure_dispatcher.
