[PATCH 4/4] PCI: uniphier-ep: Convert unused BAR_RESERVED to BAR_DISABLED for Pro5

[Manikanta Maddireddy <mmaddireddy@nvidia.com>]

On Uniphier Pro5, BAR_4 and BAR_5 are not the high half of a 64-bit
BAR (BAR_4 has no only_64bit set) and are not HW-backed; they are
unused. Convert them from BAR_RESERVED to BAR_DISABLED. Add comments
for BAR_1 and BAR_3 to clarify they are the high halves of 64-bit
BAR0 and BAR2.
