sh: add the sh_ prefix to early platform symbols

Old early platform device support is now sh-specific. Before moving on
to implementing new early platform framework based on real platform
devices, prefix all early platform symbols with 'sh_'.

drivers: move the early platform device support to arch/sh

SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.

In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.

Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.

sh_eth: remove sh_eth_plat_data::edmac_endian

Since the commit 888cc8c20cf ("sh_eth: remove EDMAC_BIG_ENDIAN") (geez,
I didn't realize that was 2 years ago!) the initializers in the SuperH
platform code for the 'sh_eth_plat_data::edmac_endian' stopped to matter,
so we can remove that field for good (not sure if it was ever useful --
SH7786 Ether has been reported to have the same EDMAC descriptor/register
endiannes as configured for the SuperH CPU)...

SH7619: fix Ether support

The 'sh_eth' driver's probe will crash as the platform code is hopelessly behind

Strangely, both commit d88a3ea6fa4c (SH7619 add ethernet controler support) that
added the platform code and commit 71557a37adb5 ([netdrvr] sh_eth: Add SH7619
support) were done in about the same time, yet the latter one added 'struct
sh_eth_plat_data' and the platform code didn't ever get updated...

sh: rework ipr code

This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.

One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.
