mfd: axp20x: Do not sleep in the power off handler
[ Upstream commit 3f37d4f695cff180033254b9ed5adc8ab927cba9 ]
Since commit 856c288b0039 ("ARM: Use do_kernel_power_off()"), the
function axp20x_power_off() now runs inside a RCU read-side critical
section, so it is not allowed to call msleep(). Use mdelay() instead.
Fixes: 856c288b0039 ("ARM: Use do_kernel_power_off()")
