[PATCH 2/5] riscv: alternatives: Remove unnecessary define and unused struct

[Andrew Jones <ajones@ventanamicro.com>]

A define and a struct were introduced with commit 6f4eea90465a
("riscv: Introduce alternative mechanism to apply errata solution"),
which introduced alternatives to RISC-V. The define is used for
an arbitrary string length, specific to sifive errata, so just use
the number directly there instead. The struct has never been used,
so remove it.
