Grzegorz Jaszczyk 3511b71db3 devices: cmos: fix register index sizes to prevent overwriting ACPI FADT regs 
According to ACPI specification the RTC's DAY_ALRM, MON_ALRM and CENTURY
are all 8-bits values. Fix the related register sizes in order to
prevent other ACPI FADT fields overwriting happen e.g. in
x86_64/src/acpi.rs:
  facp.write(FADT_FIELD_RTC_CENTURY, devices::cmos::RTC_REG_CENTURY);

While introducing this change, convert other RTC_REG* consts to u8.

This commit fixes CL:4364558 which accidentally causes some other ACPI FADT
overwriting e.g. FADT FLAGS which introduced regression in borealis project.

BUG=b:279563028
TEST=Run borealis VM and make sure that rendering issues after
suspend/resume cycle are gone.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
