x86/cpuid: Remove obsolete CPUID(0x2) iteration macro

Browse Source 
The CPUID(0x2) cache descriptors iterator at <cpuid/leaf_0x2_api.h>:

    for_each_leaf_0x2_desc()

has no more call sites.  Remove it.

* Loop over the 1-byte descriptors in the passed leaf 0x2 output registers

* u8 *desc;
*
* cpuid_get_leaf_0x2_regs(&regs);
* for_each_leaf_0x2_desc(regs, desc) {
