treewide: convert WiFi caldata size and offset to hexadecimal
This changes size and offset set for WiFi caldata extraction and
MAC address adjustment to hexadecimal notation.

This will be much clearer for the reader when numbers are big, and
will also match the style used for mtd-cal-data in DTS files.

Since dd cannot deal with hexadecimal notation, one has to convert
back to decimal by simple $(($hexnum)).
