[PATCH v3] ARM: OMAP1/2: clock: Remove unused mpurate cmdline option

[tony@atomide.com (Tony Lindgren)]

* Andrew Murray <amurray@embedded-bits.co.uk> [170123 14:05]:
> The 'mpurate' option, historically used for specifying an initial
> MPU rate at boot, no longer has any effect due to the supporting
> code being removed as it was 'wrong and dangerous' [1].
> 
> This patch removes the remaining dead code associated with the
> __setup macros to avoid confusion and reduce bloat.

> Changes since v1:

> Changes since v2:

>  * Add missing Signed-off-by
