cpufreq: pcc-cpufreq: Fix doorbell.access_width Commit 920de6ebfab8 (ACPICA: Hardware: Enhance acpi_hw_validate_register() with access_width/bit_offset awareness) apparently exposed a latent bug, doorbell.access_width is initialized to 64, but per Lv Zheng, it should be 4, and indeed, making that change does bring pcc-cpufreq back to life.
