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: ce753ad1549c ("platform: finally disallow IRQ0 in platform_get_irq() and its ilk")

The SH RTC support has an extra level of indirection to provide
either the old read_persistent_clock/update_persistent_clock
interface or the rtc-generic device for hctosys/systohc.
Both do the same thing for dreamcast, so we can do away with the
abstraction and simply let the RTC core code to take care of it.

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.
Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.
