kcpuid --all --detail claims that all bits belong to ECX, in the form
of the header CPUID_${leaf}_ECX[${subleaf}].
Print the correct register name for all CPUID output.
kcpuid --detail also dumps the raw register value if a leaf/subleaf is
covered in the CSV file, but a certain output register within it is not
covered by any CSV entry. Since register names are now properly printed,
and since the CSV file has become exhaustive using x86-cpuid-db, remove
that value dump as it pollutes the output.
While at it, rename decode_bits() to show_reg(). This makes it match its
show_range(), show_leaf() and show_reg_header() counterparts.
