Subject: [PATCH v3 3/4] arm64: dts: exynos2200: increase the size of all syscons

As IP cores are aligned by 0x10000, increase the size of all system
register instances to the maximum (0x10000) to allow using accessing
registers over the currently set limit.

Suggested-by: Sam Protsenko <semen.protsenko@...aro.org>

Did not add the r-b from Sam, as the patch is pretty much completely
reworked, including the description. Please send it again :).
