The string 'riscv64' is a generic descriptor for the 64-bit RISC-V ISA,
and can mean different things under different contexts. In the case of
tune-riscv.inc, it has served as an alias for the 'riscv64gc' profile
which packages are typically built against, resulting in the following
output (from a typical bitbake preamble):

|TUNE_FEATURES        = "rv 64 i m a f d c zicsr zifencei"

Modify tune-riscv.inc to avoid overloading the 'riscv64' string in this
way, instead setting DEFAULTTUNE to 'riscv64gc', and changing other
occurrences to match. TUNE_FEATURES remains the same under this
adjustment, but the .inc file is clearer which profile is being
targeted.
