Subject: [PATCH 2/5] mfd/stmpe: Move struct stmpe_variant_info to linux/mfd/stmpe.h

From: Pratyush Anand <pratyush.anand@...com>

Some variants like GPIO of STMPE801 have different register definition. So,
variant ID will be needed by stmpe-gpio.c to distinguish between STMPE801. Move
this struct definition from drivers/mfd/stmpe.h to include/linux/stmpe.h

Signed-off-by: Pratyush Anand <pratyush.anand@...com>
