Merge tag 'renesas-cleanup2-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/renesas

From Simon Horman:
Second round of Renesas ARM based SoC cleanups for v3.12

* Remove mach/hardware.h which has no useful contents
* Remove ag5evm board support
* Remove kota2 board support
* Use pm-rmobile on sh7372 and r8a7740 SoCs only, it is otherwise unneeded
* Remove use of INTC header on r8a7779 and r8a7740 SoCs
* Cleanup registration of usb phy in r8a7779 SoC
* Remove '0x's from R8A7779 DTS file for r8a7779 SoC

* tag 'renesas-cleanup2-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: (74 commits)

This option enables build of the LED TPU platform driver,
suitable to drive any TPU channel on newer Renesas SoCs.
The driver controls the GPIO pin connected to the LED via
the GPIO framework and expects the LED to be connected to
a pin that can be driven in both GPIO mode and using TPU
pin function. The latter to support brightness control.
Brightness control is supported but hardware blinking is not.
