platform/x86: mlx-platform: remove an unused variable

The only reference to the mlxplat_mlxcpld_psu[] array got removed,
so there is now a warning from clang:

drivers/platform/x86/mlx-platform.c:322:30: error: variable 'mlxplat_mlxcpld_psu' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
static struct i2c_board_info mlxplat_mlxcpld_psu[] = {

Remove the array as well and adapt the ARRAY_SIZE() call
accordingly.
