[PATCH v6 05/12] tee: increase TEE_MAX_ARG_SIZE to 4096

[Amirreza Zarrabi]

Increase TEE_MAX_ARG_SIZE to accommodate worst-case scenarios where
additional buffer space is required to pass all arguments to TEE.
This change is necessary for upcoming support for Qualcomm TEE, which
requires a larger buffer for argument marshaling.
