Juergen Gross c3719bc074 x86: make get_cpu_vendor() accessible from Xen code 
commit efbcd61d9bebb771c836a3b8bfced8165633db7c upstream.

In order to be able to differentiate between AMD and Intel based
systems for very early hypercalls without having to rely on the Xen
hypercall page, make get_cpu_vendor() non-static.

Refactor early_cpu_init() for the same reason by splitting out the
loop initializing cpu_devs() into an externally callable function.

This is part of XSA-466 / CVE-2024-53241.
