regmap: kunit: Fix warnings of implicit casts to __le16 and __be16

Fix warnings about implicit casts to __le16 and __be16 types reported
by smatch:

drivers/base/regmap/regmap-kunit.c:1118:25:
warning: cast to restricted __be16
drivers/base/regmap/regmap-kunit.c:1120:25:
warning: cast to restricted __le16
drivers/base/regmap/regmap-kunit.c:1187:33:
warning: cast to restricted __be16
drivers/base/regmap/regmap-kunit.c:1190:33:
warning: cast to restricted __le16
drivers/base/regmap/regmap-kunit.c:1302:33:
warning: cast to restricted __be16
drivers/base/regmap/regmap-kunit.c:1305:33:
warning: cast to restricted __le16

Perform a __force cast for all these.
