[PATCH 06/10] ARM: shmobile: Remove shmobile_setup_delay()

From: Magnus Damm <damm+renesas at opensource.se>
All ARM mach-shmobile SoCs and boards now rely on DTS for
CPU Frequency information, so remove the unused function
shmobile_setup_delay(). While at it, make the function
shmobile_setup_delay_hz() static.
