clk: sifive: restrict Kconfig scope for the FU540 PRCI driver

paul-walmsley-sifive · bebarino · commit f7df8c92b4b9 · 2019-05-21T11:34:45.000-07:00
Restrict Kconfig scope for SiFive clock and reset IP block drivers
such that they won't appear on most configurations that are unlikely
to support them.  This is based on a suggestion from Pavel Machek
&lt;pavel@ucw.cz&gt;.  Ideally this should be dependent on
CONFIG_ARCH_SIFIVE, but since that Kconfig directive does not yet
exist, add dependencies on RISCV or COMPILE_TEST for now.
