Subject: [PATCH v3 0/3] MediaTek Security random number generator support

These patch series introduce a generic rng driver for Trustzone
based kernel driver which would like to communicate with ATF
SIP services.

Patch #1 initials SMC fid table for Mediatek SIP interfaces and
adds HWRNG related SMC call.

Patch #2..3 adds mtk-sec-rng kernel driver for Trustzone based SoCs.
For MediaTek SoCs on ARMv8 with TrustZone enabled, peripherals like
entropy sources is not accessible from normal world (linux) and
rather accessible from secure world (ATF/TEE) only. This driver aims
to provide a generic interface to ATF rng service.


changes since v1:
- rename mt67xx-rng to mtk-sec-rng since all MediaTek ARMv8 SoCs
can reuse this driver.
- refine coding style and unnecessary check.

changes since v2:
- remove unused comments.
- remove redundant variable.

  hwrng: add mtk-sec-rng driver
