This patch adds support for getting the SoC name string
using the SMCCC_ARCH_SOC_ID interface. The SoC name query
was introduced in SMCCC version 1.6. It is available only
through SMC64 calls.
A new function ID, SMCCC_GET_SOC_NAME, is added. It returns
the SoC name as a null-terminated ASCII string, spread across
registers X1 to X17 in little endian order.
The total length is 136 bytes, including the null byte.
Any space after the null terminator is filled
with zeros.
A platform hook plat_get_soc_name() is added to return the
SoC name. A weak default version is also provided that returns
SMC_ARCH_CALL_NOT_SUPPORTED for platforms that do not support
this feature.
The name should follow the SMCCC rule that it must not expose
any information that is not already reported
by the SoC version and revision calls.
