With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the opposite thing from older versions of gcc
(emits code for an externally linkable version of the inline function).
"static inline" does the intended behavior in all cases instead.
Description taken from:
"staging, rtl8192e, LLVMLinux: Change extern inline to static inline"
(sha1: 6d91857d48)

Add missing param.h header because of HZ macro.
It is causing compilation failure:
In file included from include/linux/delay.h:14:0,
from drivers/clk/qcom/reset.c:18:
drivers/clk/qcom/reset.c: In function 'qcom_reset':
arch/microblaze/include/asm/delay.h:39:35: error: 'HZ'
undeclared (first use in this function)
