arm-bsp/trusted-firmware-m: corstone-1000: Increase PS_MAX_ASSET_SIZE and CRYPTO_IOVEC_BUFFER_SIZE for EFI variable support

Increase `PS_MAX_ASSET_SIZE` and `CRYPTO_IOVEC_BUFFER_SIZE` for the
Corstone-1000 platform to support large EFI variable storage required
by the UEFI firmware update flow and to pass Arm Architecture Compliance
Suite (ACS) tests.

Subject: [PATCH 2/2] Platform: Corstone1000: Increase buffer sizes
Increase PSA_MAX_ASSET_SIZE and CRYPTO_IOVEC_BUFFER_SIZE
to accommodate large size EFI variables set by new U-Boot version.
This change is required to pass ACS tests related to Set/Get
EFI variables. These ACS tests started failing after introducing new
version of U-Boot, Trusted-Services and Trusted-Firmware-M while
implementing PSA FWU support.
