i2c: mlxbf: Fix frequency calculation
[ Upstream commit 37f071ec327b04c83d47637c5e5c2199b39899ca ]
The i2c-mlxbf.c driver is currently broken because there is a bug
in the calculation of the frequency. core_f, core_r and core_od
are components read from hardware registers and are used to
compute the frequency used to compute different timing parameters.
The shifting mechanism used to get core_f, core_r and core_od is
wrong. Use FIELD_GET to mask and shift the bitfields properly.
