riscv: sifive: Rename sifive_prci.{c, h} to sifive_e_prci.{c, h}

Current SiFive PRCI model only works with sifive_e machine, as it
only emulates registers or PRCI block in the FE310 SoC.

Rename the file name to make it clear that it is for sifive_e.
This also prefix "sifive_e"/"SIFIVE_E" for all macros, variables
and functions.
