[MIPS] Delete now-unreferenced i2c-yosemite.h header file.
Given that the corresponding source file i2c-yosemite.c file was removed in commit daa4a68f901c4d6491baa1a01f5c869a553c3f6c, and that no one else includes this file, it seems safe to delete it. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
