The `interrupts` property indicates an RTC alarm interrupt, which is
required for RTCs that support the alarm feature, which is not supported
by the Loongson-1C RTC. We exclude it for a more accurate description.
Changing the `allowed` property is ABI-breaking behavior, but
throughout the existing Loongson DTS{i}, the description of the RTC
nodes conforms to the modified bingding rules.
Thus, the existing Loongson DTS{i} will not be affected.

With multiple virtio crypto devices supported with different NUMA
nodes, when crypto session is created, it will search virtio crypto
device with the same numa node of current CPU.
Here API topology_physical_package_id() is replaced with cpu_to_node()
since package id is physical concept, and one package id have multiple
memory numa id.

When VM boots with one virtio-crypto PCI device and builtin backend,
run openssl benchmark command with multiple processes, such as
openssl speed -evp aes-128-cbc -engine afalg -seconds 10 -multi 32
openssl processes will hangup and there is error reported like this:
virtio_crypto virtio0: dataq.0:id 3 is not a head!
It seems that the data virtqueue need protection when it is handled
for virtio done notification. If the spinlock protection is added
in virtcrypto_done_task(), openssl benchmark with multiple processes
works well.

The divider_round_rate() function is now deprecated, so let's migrate
to divider_determine_rate() instead so that this deprecated API can be
removed.
Note that when the main function itself was migrated to use
determine_rate, this was mistakenly converted to:
req->rate = divider_round_rate(...)
This is invalid in the case when an error occurs since it can set the
rate to a negative value.

Document the clock controller shipped in Loongson-2K0300 SoC, which
generates various clock signals for SoC peripherals. Differing from
previous generations of SoCs, LS2K0300 requires a 120MHz external clock
input.
