Move the Trusted Foundations support out of arch/arm/firmware and into
drivers/firmware where most other firmware support implementations are
located.

- * Support for the Trusted Foundations secure monitor.
- *
- * Trusted Foundation comes active on some ARM consumer devices (most
- * Tegra-based devices sold on the market are concerned). Such devices can only
- * perform some basic operations, like setting the CPU reset vector, through
- * SMC calls to the secure monitor. The calls are completely specific to
- * Trusted Foundations, and do *not* follow the SMC calling convention or the
- * PSCI standard.
