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



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

    for_each_leaf_0x2_desc()

has no more call sites.  Remove it.

/**

 * for_each_leaf_0x2_desc() - Iterator for CPUID leaf 0x2 descriptors

 * @regs:	Leaf 0x2 output, as returned by cpuid_get_leaf_0x2_regs()

 * @desc:	Pointer to the returned descriptor for each iteration

 *

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

 * @regs.  Provide each descriptor through @desc.

 *

 * Note that the first byte is skipped as it is not a descriptor.

 *

 * Sample usage::

 *

 *	union leaf_0x2_regs regs;

 *	u8 *desc;

 *

 *	cpuid_get_leaf_0x2_regs(&regs);

 *	for_each_leaf_0x2_desc(regs, desc) {

 *		// Handle *desc value

 *	}
