* Assume eMMC for CM4/CM5 non-lite
Attempt the fast path by skipping the SD interface condition command timeout on CM4/CM5 (non-lite) modules and enable eMMC mode directly. This saves ~250ms of the boot time.
* Don't stomp on RTC alarm state
Preserve the RTC's alarm state so that it can be queried by the rpi-rtc
driver.

* arm_loader: Apply rpifwcrypto lock permissions GET/SET USER OTP
Previously, the GET/SET user OTP mailboxes would provide access to the
device unique private key. Update the mailbox API to fail if the
key has been locked via lock_device_private_key=1 in config.txt or
the associated mailbox call.
GET/SET user OTP fails by setting the result tag to the standard
error code (0x80000000). The dedicate GET/SET private key continue
to fail the entire mailbox operation to force vcmailbox to exit
with a non-zero error code.
