[linuxsh-dev] SCI/SCIF console bug fix (long standing bug)

[NIIBE Y. <gn...@m1...>]

Using serial console, sometimes we see garbage data at the beginning.
The cause is udelay in the initialization routine of sh-sci.c.  The
initialization will be called before the calibration of
loops_per_jiffy.  I put big value there.

	* arch/sh/kernel/setup.c (boot_cpu_data): Let have initial value
	for loops_per_jiffy.
