[PATCH v2 1/1] clk: sifive: Fix W=1 kernel build warning

[Zong Li]

This commit reverts commit 487dc7bb6a0c ("clk: sifive: fu540-prci:
Declare static const variable 'prci_clk_fu540' where it's used").
For fixing W=1 kernel build warning(s) about ‘prci_clk_fu540’ defined
but not used [-Wunused-const-variable=], the problem is that the C file
of fu540 and fu740 doesn't use these variables, but they includes the
header files. We could refine the code by moving the definition of these
variable into fu540 and fu740 implementation respectively, instead of
common core code, then we could still separate the SoCs-dependent data
in their own implementation.
