ARM: mach-shmobile: Kota2 TPU LED platform data
This patch updates the Kota2 board support code to use the recently merged TPU LED driver whenever possible. The sh73a0 SoC has 5 TPU hardware blocks each with 4 timer channels which in theory allows a total of 20 LEDs to be controlled by "leds-renesas-tpu" driver instances. The Kota2 board has 4 LEDs connected to GPIO pins that also come with TPU pin functions, so this patch ties up these 4 LEDS and leaves the remaining 3 LEDS for the GPIO based LED driver.
