ARM: shmobile: sh7372: Switch to new style CMT device

The CMT (Compare Match Timer) driver implements a new style of platform
data that handles the timer as a single device with multiple channel.
Switch from the old-style platform data to the new-style platform data.

usb: host: xhci-plat: add clock support

Some platforms (such as the Armada 38x ones) can gate the clock of
their USB controller. This patch adds the support for one clock in
xhci-plat, by enabling it during probe and disabling it on remove.

To achieve this, it adds a 'struct clk *' member in xhci_hcd. While
only used for now in xhci-plat, it might be used by other drivers in
the future. Moreover, the xhci_hcd structure already holds other
members such as msix_count and msix_entries, which are MSI-X specific,
and therefore only used by xhci-pci.
