Subject: [PATCH] drm/amd/display: Use true/false for boolean variables in DML2
 core files

Replace 0 and 1 with false and true for boolean variables in
dml2_core_dcn4_calcs.c and dml2_core_utils.c to align with the Linux
kernel coding style guidelines, which recommend using C99 bool type
with true/false values.
