Sergey Shtylyov f5d7f9e155 sh: Avoid using IRQ0 on SH3 and SH4 
[ Upstream commit a8ac296114 ]

IRQ0 is no longer returned by platform_get_irq() and its ilk -- they now
return -EINVAL instead.  However, the kernel code supporting SH3/4-based
SoCs still maps the IRQ #s starting at 0 -- modify that code to start the
IRQ #s from 16 instead.

The patch should mostly affect the AP-SH4A-3A/AP-SH4AD-0A boards as they
indeed are using IRQ0 for the SMSC911x compatible Ethernet chip.

Fixes: ce753ad154 ("platform: finally disallow IRQ0 in platform_get_irq() and its ilk")
