[PATCH for-fixes] MIPS: Loongson64: Do not override watch and ejtag feature
From: Jiaxun Yang
Date: Sat Aug 08 2020 - 08:33:14 EST
Do not override ejtag feature to 0 as Loongson 3A1000+ do have ejtag.
For watch, as KVM emulated CPU doesn't have watch feature, we should
not enable it unconditionally.
Signed-off-by: Jiaxun Yang <jiaxun.yang@xxxxxxxxxxx>

This patch should go into mips-fixes tree as watch feature is blocking
KVM guest boot in some cases.
