Subject: pwm: imx27: Use 64-bit division macro
Git-commit: 1689dcd433aaa0d32dec3fdb4bd166a0d38f4bbf
Patch-mainline: v5.9-rc1
References: jsc#SLE-16106
Since the PWM framework is switching struct pwm_state.period's
datatype to u64, prepare for this transition by using
DIV_ROUND_UP_ULL to handle a 64-bit dividend.
