Adds support for:
* PSCI_FEATURES, which was introduced in PSCI 1.0. This provides API
that allows discovering whether a specific PSCI function is implemented
and its features.
* SYSTEM_RESET2, which was introduced in PSCI 1.1, which extends existing
SYSTEM_RESET. It provides support for vendor-specific resets, providing
reset_type as an additional param.

For additional details visit [1].

Implementations of some functions were borrowed from Linux PSCI driver
code [2].

This introduces strlcat, which provides a safer interface than strncat. It
never copies more than its size bytes, including the terminating nul. In
addition, it never reads past dest[size - 1], even if dest is not
nul-terminated.

This also removes the stub for dwc3 now that we have a proper
implementation.

We need to allow SoCs to create their own drivers for this so that they
can use their own of-platdata structs. To minimise code duplication,
export the driver operations and the ofdata_to_plat() setup function.

In drivers we use a family of printing functions including pr_err() and
pr_cont(). CONFIG_LOGLEVEL is used to control which of these lead to output
via printf().

Our logging functions allow finer grained control of output. So replace
printf() by the matching logging functions. The usage of CONFIG_LOGLEVEL
remains unchanged.
