This patch adds directory for SH-2007 support and modify tools/mach-types.
mach-sh2007/setup.c ... Setup platform devices and provide machine vector.
tools/mach-types ... Added entry of SH2007 for mach_is_sh2007()

CAUTION: IDE support is not tested yet.
	 I'll be able to obtain cable for 2.5 inch HDD,
	 then I'll test this device.

v2:
 * Pending onboardio.c, for dip switch reading and LED manipulating.
   Because these deviced should be treated in more unified way
   such as LED device class. Creating /dev/dipsw is dirty.
   But the LED device is not physical device, it exists logicaly.
   I'm pending my decision about treating dip switch and logical LED temporary.
 * Cleaning. setup.c of v1 did lots of non board specific
   (processor specific) things. According to Paul's advice, I reduced them.
   And sh2007_init_irq() uses interrupt setting of 7780 specific.

v3:
 * According to Magnus's advice, removed meaningless function release_platform_dev()
   and #if 0 ... #endif for IDE support.
 * This patch contains Nobuhiro-san's one to generate mach_is_sh2007() in include/generated/machtypes.h
