[PATCH] input: touchscreen: wdt87xx_i2c: Replace mdelay() with msleep() in wdt87xx_resume()

[Jia-Ju Bai]

wdt87xx_resume() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

This is found by a static analysis tool named DCNS written by myself.
