aspeed: Refactor AST2500 RAM Driver and Sysreset Driver

This change switches all existing users of ast2500 Watchdog to Driver
Model based Watchdog driver.

To perform system reset Sysreset Driver uses first Watchdog device found
via uclass_first_device call. Since the system is going to be reset
anyway it does not make much difference which watchdog is used.

Instead of using Watchdog to reset itself, SDRAM driver now uses Reset
driver to do that.

These were the only users of the old Watchdog API, so that API is
removed.

This all is done in one change to avoid having to maintain dual API for
watchdog in between.

dm: core: Replace of_offset with accessor

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

aspeed: Add basic ast2500-specific drivers and configuration

Clock Driver

This driver is ast2500-specific and is not compatible with earlier
versions of this chip. The differences are not that big, but they are
in somewhat random places, so making it compatible with ast2400 is not
worth the effort at the moment.

SDRAM MC driver

The driver is very ast2500-specific and is completely incompatible
with previous versions of the chip.

The memory controller is very poorly documented by Aspeed in the
datasheet, with any mention of the whole range of registers missing. The
initialization procedure has been basically taken from Aspeed SDK, where
it is implemented in assembly. Here it is rewritten in C, with very limited
understanding of what exactly it is doing.
