The LPC controller has no concept of the BMC and the Host partitions.

A concrete instance is that the HICRB[5:4] are for the I/O port address
configurtaion of KCS channel 1/2. However, the KCS driver cannot access
HICRB for channel 1/2 initialization via syscon regmap interface due to
the parition boundary. (i.e. offset 80h)

In addition, for the HW design backward compatibility, a newly added HW
control bit could be located at any reserved one over the LPC addressing
space. Thereby, this patch removes the lpc-bmc and lpc-host child node
and thus the LPC partitioning.

Note that this change requires the synchronization between device tree
change and the driver change. To prevent the misuse of old devicetrees
with new drivers, or vice versa, the v2 compatible strings are adopted
for the LPC device as listed:

	"aspeed,ast2400-lpc-v2"
	"aspeed,ast2500-lpc-v2"
	"aspeed,ast2600-lpc-v2"

There is a timer wrap issue on dra7 for the ARM architected timer.
In a typical clock configuration the timer fails to wrap after 388 days.

To work around the issue, we need to use timer-ti-dm percpu timers instead.

Let's configure dmtimer3 and 4 as percpu timers by default, and warn about
the issue if the dtb is not configured properly.

Let's do this as a single patch so it can be backported to v5.8 and later
kernels easily. Note that this patch depends on earlier timer-ti-dm
systimer posted mode fixes, and a preparatory clockevent patch
"clocksource/drivers/timer-ti-dm: Prepare to handle dra7 timer wrap issue".
