include/device: Fix IO resource handling covering 0xFFFF
IO resource creation utils taking 'from' and 'to' as parameters
use uint16_t for them, where 'to' equals the resource limit plus
1. When a resource is with a limit of 0xFFFF, the value of 'to'
will be clipped to 0x0000 by uint16_t. Fix this problem by use
uint32_t and checks the effective range to make sure it no larger
than UINT16_MAX + 1.
