arm-bsp/corstone1000: Fix RSA key generation issue

Browse Source 
This support is for Cassini distro using Corstone-1000 platform.

When running parsec test, it reports an error
`PSA_ERROR_DATA_INVALID (-153)`.

This is related to `ITS_MAX_ASSET_SIZE` configuration which is been
set to 512 on the secure enclave (TF-M), which defines the max asset
size and it overflows when running the parsec tests.

The key is generated, but when it is asked to store via `psa_its_set`
it returns `PSA_ERROR_INVALID_ARGUMENT (-135)`, which then propagates
to `PSA_ERROR_DATA_INVALID (-153)`

Increasing the `ITS_MAX_ASSET_SIZE` to 2048 solves this issue.
