ARM: shmobile: Remove shmobile_setup_delay()
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. Signed-off-by: Magnus Damm <damm+renesas@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
