dtc: Remove obsolete check_properties() function
dtc: Remove obsolete check_properties() function

After the last couple of patches converting various old-style semantic
checks to the new framework, the only thing that the old-style
check_properties() function still checks is that the size of "reg"
properties is a multiple of the cell size.

This patch removes check_properties() and all related code and data.
The check on the size of reg properties is folded into the existing
check for the format of "reg" properties (still old-style for the time
being).
