The symbol "SM" is a library symbol and should not be prompted for. It
should be selected by the drivers that use it. In this case we need to
add a SANDBOX_SM symbol for the sandbox driver. The meson SM driver
cannot build on other platforms, so add the appropriate dependency.

At the moment, we don't have a common API for working with
SM, only the smc_call() function. This approach is not generic
and difficult to configure and maintain.
This patch adds UCLASS_SM with the generic API:
- sm_call()
- sm_call_write()
- sm_call_read()
These functions operate with struct pt_regs, which describes
Secure Monitor arguments.
