io.h: add io_mask{8,16,32} functions

When writing peripheral drivers, there's very often a need to read a
register value, set/clear some bits and then write the new value
back. Instead of having to 'manually' call read, do bit manipulations
and write every single time, add this helper function for convenience.

core: secure storage: dual filesystems support

Adds support for multiple filesystems by keeping a pointer to
tee_file_operations in the tee_pobj and tee_storage_enum structures.

Two identifiers are added to the API to be used as the storage_id
parameter, so that TAs may dynamically choose the filesystem:
- TEE_STORAGE_PRIVATE_REE (requires CFG_REE_FS=y)
- TEE_STORAGE_PRIVATE_RPMB (requires CFG_RPMB_FS=y)
The value TEE_STORAGE_PRIVATE will select the REE FS if available,
otherwise RPMB. At least one FS has to be enabled at build time. Only
the REE filesystem is enabled by default.
