pc: fix regression for 64 bit PCI memory
commit 398489018183d613306ab022653552247d93919f
pc: limit 64 bit hole to 2G by default
introduced a way for management to control
the window allocated to the 64 bit PCI hole.
This is useful, but existing management tools do not know how to set
this property. As a result, e.g. specifying a large ivshmem device with
size > 4G is broken by default. For example this configuration no
longer works:
-device ivshmem,size=4294967296,chardev=cfoo
-chardev socket,path=/tmp/sock,id=cfoo,server,nowait
Fix this by detecting that hole size was not specified
and defaulting to the backwards-compatible value of 1 << 62.
