riscv: hwprobe: fix invalid sign extension for RISCV_HWPROBE_EXT_ZVFHMIN
[ Upstream commit 5ea6764d9095e234b024054f75ebbccc4f0eb146 ]
The current definition yields a negative 32bits signed value which
result in a mask with is obviously incorrect. Replace it by using a
1ULL bit shift value to obtain a single set bit mask.
