m5206_mbar_width has 0x80 elements and supports 0 <= offset < 0x200.

Checked against the data sheet -- last documented register is at offset $1F0,
so correcting the offset check rather than the array length is the correct
fix.

Then m5206_mbar_width should be shortened to 124 elements
(0x1f0 / 4) _and_ the offset check needs a correction.
