PCI: endpoint: pci-epf-vntb: Simplify ctrl/SPAD space allocation
When allocating the shared ctrl/SPAD space, epf_ntb_config_spad_bar_alloc()
should not try to handle the size quirks for underlying BAR, whether it is
fixed size or alignment. This is already handled by pci_epf_alloc_space().
Also, when handling the alignment, this allocates more space than
necessary. For example, with a SPAD size of 1024B and a ctrl size of 308B,
the space necessary is 1332B. If the alignment is 1MB,
epf_ntb_config_spad_bar_alloc() tries to allocate 2MB where 1MB would have
been more than enough.
Drop the handling of the BAR size quirks and let pci_epf_alloc_space()
handle that. Just make sure the 32bits SPAD register are aligned on 32bits.
