ARM: shmobile: lager: Correct setting of ethernet PHY LED mode

The correct binding is "micrel,led-mode", not "led-mode".

This corrects an error which was introduced when setting of ethernet PHY
LED mode was added by 82e62182d59bd1d0 ("ARM: shmobile: lager: Set ethernet

This makes the lager code consistent with the koelsch code which was added
by ae00d12a032490b3 ("ARM: shmobile: koelsch: Set ethernet PHY LED mode").

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.

clocksource: sh_tmu: Rename clock to "fck" in the non-legacy case

The sh_tmu driver gets the TMU functional clock using a connection ID of
"tmu_fck". While all SH SoCs create clock lookup entries with a NULL
device ID and a "tmu_fck" connection ID, the ARM SoCs use the device ID
only with a NULL connection ID. This works on legacy platforms but will
break on ARM with DT boot.

Fix the situation by using a connection ID of "fck" in the non-legacy
platform data case. Clock lookup entries will be renamed to use the
device ID as well as the connection ID as platforms get moved to new
platform data. The legacy code will eventually be dropped, leaving us
with device ID based clock lookup, compatible with DT boot.

clocksource: sh_tmu: Add support for multiple channels per device

TMU hardware devices can support multiple channels, with global
registers and per-channel registers. The sh_tmu driver currently models
the hardware with one Linux device per channel. This model makes it
difficult to handle global registers in a clean way.

Add support for a new model that uses one Linux device per timer with
multiple channels per device. This requires changes to platform data,
add new channel configuration fields.

Support for the legacy model is kept and will be removed after all
platforms switch to the new model.
