[PATCH/RFC 1/4] OMAP3: PM debug: remove sleep_while_idle feature

[Kevin Hilman <khilman@ti.com>]

Remove the OMAP-specific PM debug 'sleep_while_idle' feature which is
currently available as an OMAP-specific debugfs entry.

This duplicates existing ARM-generic functionality available as a
boot-time option using the boot cmdline option 'hohlt'.

If runtime configuration of this is needed, then adding a debugfs
entry for the ARM-generic hlt/nohlt interface should be added.
