riscv: alternatives: Don't name unused macro parameters

commit 2946546a5a9a3385aee3056efa95d29483c5df66 from
https://github.com/linux4microchip/linux.git

 linux-6.1-mchp+fpga

Without CONFIG_RISCV_ALTERNATIVE only the first parameter of the
ALTERNATIVE macros is needed. Use ... for the rest to cut down on
clutter. While there, fix a couple space vs. tab issues.
