Kuninori Morimoto ff4a7481c3 sh: drivers: convert to SPDX identifiers
Update license to use SPDX-License-Identifier instead of verbose license
text.

As original license mentioned, it is GPL-2.0 in SPDX.
Then, MODULE_LICENSE() should be "GPL v2" instead of "GPL".
See ${LINUX}/include/linux/module.h

	"GPL"		[GNU Public License v2 or later]
	"GPL v2"	[GNU Public License v2]
