Jinqian Yang e506751b7d arm64: Add support for HIP09 Spectre-BHB mitigation 
[ Upstream commit e18c09b204 ]

The HIP09 processor is vulnerable to the Spectre-BHB (Branch History
Buffer) attack, which can be exploited to leak information through
branch prediction side channels. This commit adds the MIDR of HIP09
to the list for software mitigation.
