PCI: Correct the resource_alignment parameter example

From: Alexey Kardashevskiy
Date: Wed Jun 05 2019 - 23:38:39 EST

The option description requires an order and so does the option
parsing code, however the example uses a size, fix this.

[<order of align>@]<pci_dev>[; ...]
Specifies alignment and device to reassign
aligned memory resources. How to
specify the device is described above.
If <order of align> is not specified,
PAGE_SIZE is used as alignment.
PCI-PCI bridge can be specified, if resource
windows need to be expanded.
To specify the alignment for several
instances of a device, the PCI vendor,
device, subvendor, and subdevice may be
- specified, e.g., 4096@pci:8086:9c22:103c:198f
+ specified, e.g., 12@pci:8086:9c22:103c:198f
+ for the 4096 alignment.
ecrc= Enable/disable PCIe ECRC (transaction layer
end-to-end CRC checking).
bios: Use BIOS/firmware settings. This is the
the default.
off: Turn ECRC off
on: Turn ECRC on.
hpiosize=nn[KMG] The fixed amount of bus space which is
reserved for hotplug bridge's IO window.
Default size is 256 bytes.
hpmemsize=nn[KMG] The fixed amount of bus space which is
reserved for hotplug bridge's memory window.
Default size is 2 megabytes.
hpbussize=nn The minimum amount of additional bus numbers
