Although that this is functionally equivalent (since 'Zvfhmin' implies 'Zve32f'), it makes clearer that 'Zvfh' is a strict superset of 'Zvfhmin'. Signed-off-by: Tsukasa OI <research_trasio@irq.a4lg.com>

Although that this is functionally equivalent (since
Zvfhmindepends onZve32f), it makes clearer thatZvfhis a strict superset ofZvfhmin.Again, it will not change the contents of both extensions.
But I believe that this change will ease some developers that depend on the expanded ISA string (e.g. after expanding
G→IMAFD_Zicsr_Zifencei) or similar data structure (like which QEMU uses) because if we need to probe the vector FP16 conversion capability, we just need to probe for theZvfhminextension, notZvfhminorZvfh.
