soc/amd/picasso/cpu: use CPUID_ALL_STEPPINGS_MASK
Use CPUID_ALL_STEPPINGS_MASK to only need one CPU device ID table entry
per family & model combination and not one per stepping.
TEST=Mandolin with a Picasso APU with PICASSO_B1_CPUID (0x00810f81)
still finished mpinit and boots successfully even though now only
PICASSO_B0_CPUID (0x00810f80) with CPUID_ALL_STEPPINGS_MASK specified as
device match mask. When commenting out the line with PICASSO_B0_CPUID
as a negative test, mpinit fails as expected.
