H.J. Lu f53ffc9b90 x86: Handle _SC_LEVEL1_ICACHE_LINESIZE [BZ #27444] 
commit 2d651eb926
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Fri Sep 18 07:55:14 2020 -0700

    x86: Move x86 processor cache info to cpu_features

missed _SC_LEVEL1_ICACHE_LINESIZE.

1. Add level1_icache_linesize to struct cpu_features.
2. Initialize level1_icache_linesize by calling handle_intel,
handle_zhaoxin and handle_amd with _SC_LEVEL1_ICACHE_LINESIZE.
3. Return level1_icache_linesize for _SC_LEVEL1_ICACHE_LINESIZE.
