arm64: avoid -Woverride-init warning
The icache_policy_str[] definition causes a warning when extra
warning flags are enabled:
arch/arm64/kernel/cpuinfo.c:38:26: warning: initialized field overwritten [-Woverride-init]
38 | [ICACHE_POLICY_VIPT] = "VIPT",
| ^~~~~~
arch/arm64/kernel/cpuinfo.c:38:26: note: (near initialization for 'icache_policy_str[2]')
arch/arm64/kernel/cpuinfo.c:39:26: warning: initialized field overwritten [-Woverride-init]
39 | [ICACHE_POLICY_PIPT] = "PIPT",
| ^~~~~~
arch/arm64/kernel/cpuinfo.c:39:26: note: (near initialization for 'icache_policy_str[3]')
arch/arm64/kernel/cpuinfo.c:40:27: warning: initialized field overwritten [-Woverride-init]
40 | [ICACHE_POLICY_VPIPT] = "VPIPT",
| ^~~~~~~
arch/arm64/kernel/cpuinfo.c:40:27: note: (near initialization for 'icache_policy_str[0]')
There is no real need for the default initializer here, as printing a
NULL string is harmless. Rewrite the logic to have an explicit
reserved value for the only one that uses the default value.
This partially reverts the commit that removed ICACHE_POLICY_AIVIVT.
