PATCH 2/2 usb: renesas_usbhs: add support for SUDMAC

The SUDMAC uses 8-bit width only. So, when the driver uses SUDMAC, we have to clear the MBW_32.

I have observed what appears to be a regression caused by this patch when booting a kernel built using shmobile_defconfig on the koelsch and lager boards.

I noticed this problem while testing next-20150129.

I have provided boot logs at the end of this email.

I have observed what appears to be a regression caused by this patch when booting a kernel built using shmobile_defconfig on the koelsch and lager boards.

Thank you for the point. I should have tested using shmobile_defconfig. So, I will submit a patch to fix this issue.

Detail:
- Since the defconfig doesn't enable CONFIG_GENERIC_PHY and CONFIG_PHY_RCAR_GEN2, the driver's probe failed.
- Since we don't have dmac for usb at the moment if we use the defconfig, dma_request_slave_channel_reason() will fail with ERR_PTR(-ENODEV).
- But, the current renesas_usbhs driver will keeps ERR_PTR(-ENODEV) in tx_chan and rx_chan. So, if the driver calls usbhs_dma_quit, the driver calls dma_release_channel() with wrong argument (ERR_PTR(-ENODEV)).
- So, I will write a patch to set tx_chan and rx_chan to NULL in the usbhsf_dma_init_dt() if these values are IS_ERR.

Best regards,
Yoshihiro Shimoda
