MIPS: Malta: Fix PCI southbridge legacy resource reservations
Covering the PCI southbridge legacy port I/O range with a northbridge
resource reservation prevents MIPS Malta platform code from claiming its
standard legacy resources. This is because request_resource() calls
cause a clash with the previous reservation and consequently fail.
Change to using insert_resource() so as to prevent the clash, switching
the legacy reservations from:
00000000-00ffffff : MSC PCI I/O
00000020-00000021 : pic1
00000070-00000077 : rtc0
000000a0-000000a1 : pic2
[...]
to:
00000000-00ffffff : MSC PCI I/O
00000000-0000001f : dma1
00000020-00000021 : pic1
00000040-0000005f : timer
00000060-0000006f : keyboard
00000070-00000077 : rtc0
00000080-0000008f : dma page reg
000000a0-000000a1 : pic2
000000c0-000000df : dma2
