Documentation: kvm: fix messy conversion from .txt to .rst 

Building the documentation gives a warning that the KVM_PPC_RESIZE_HPT_PREPARE
label is defined twice.  The root cause is that the KVM_PPC_RESIZE_HPT_PREPARE
API is present twice, the second being a mix of the prepare and commit APIs.
Fix it.

The geometries[] field gives up to 8 supported geometries for the
radix page table, in terms of the log base 2 of the smallest page
size, and the number of bits indexed at each level of the tree, from
the PTE level up to the PGD level in that order. Any unused entries
will have 0 in the page_shift field.
The ap_encodings gives the supported page sizes and their AP field
encodings, encoded with the AP value in the top 3 bits and the log
base 2 of the page size in the bottom 6 bits.

Used to implement the PAPR extension for runtime resizing of a guest's
Hashed Page Table (HPT). Specifically this starts, stops or monitors
the preparation of a new potential HPT for the guest, essentially
implementing the H_RESIZE_HPT_PREPARE hypercall.

this begins preparation of a new pending HPT of size 2^(shift) bytes.
It then returns a positive integer with the estimated number of
