net: macb: simplify macb_adj_dma_desc_idx()
The function body uses a switch statement on bp->hw_dma_cap and handles
its four possible values: 0, is_64b, is_ptp, is_64b && is_ptp.
Instead, refactor by noticing that the return value is:
desc_size * MULT
with MULT = 3 if is_64b && is_ptp,
2 if is_64b || is_ptp,
1 otherwise.
MULT can be expressed as:
1 + is_64b + is_ptp
