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.

serial: sh-sci: Compute the regshift value for SCI ports SCI instances found in SH SoCs have different spacing between registers depending on the SoC. The platform data contains a regshift field that tells the driver by how many bits to shift the register offset to compute its address. We can compute the regshift value automatically based on the memory resource size, there's no need to pass the value through platform data. Fix the sh7750 SCI and sh7760 SIM port memory resources length to ensure proper computation of the regshift value.

serial: sh-sci: Abstract register maps. This takes a bit of a sledgehammer to the horribly CPU subtype ifdef-ridden header and abstracts all of the different register layouts in to distinct types which in turn can be overriden on a per-port basis, or permitted to default to the map matching the port type at probe time. In the process this ultimately fixes up inumerable bugs with mismatches on various CPU types (particularly the legacy ones that were obviously broken years ago and no one noticed) and provides a more tightly coupled and consolidated platform for extending and implementing generic features.

While drivers/sh has already been sanitized, there is still quite a lot of code that is not.

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.
