reset: rzg2l-usbphy-ctrl: Check pwrrdy is valid before using it
The pwrrdy regmap_filed is allocated in rzg2l_usbphy_ctrl_pwrrdy_init()
only if the driver data is set to RZG2L_USBPHY_CTRL_PWRRDY. Check that
pwrrdy is valid before using it to avoid "Unable to handle kernel NULL
pointer dereference at virtual address" errors.
