[Impact]

* Request to accommodate new shape with 320 CPUs, greater than current max value of 256.

[Fix]

* Update CONFIG_NR_CPUS from 256 to 512 for arm64 arch.

[Test Case]

* Compile tested
* Boot tested

[Where things could go wrong]

* Low chance of regression. Simple config change.

[Other Info]

* Change proposed in Debian unstable (https://salsa.debian.org/kernel-team/linux/-/merge_requests/937?commit_id=8dfba66465dbf4c3c8ef8998065805b852b34e22#fc973071e6f4da49be1ec7a17e00635dd41dcaf1), but was denied due to additional kernel size. This shouldn't affect Ubuntu kernel so much as it's compressed.
* SF #00375112
