Subject: [PATCH] bcma: add HP Stream Notebook

In this laptop we have the following PCI device:
02:00.0 Network controller [0280]: Broadcom Limited BCM43142 802.11b/g/n [14e4:4365] (rev 01)
Subsystem: Hewlett-Packard Company BCM43142 802.11b/g/n [103c:804a]
[...]
Region 0: Memory at 91000000 (64-bit, non-prefetchable) [size=32K]
[...]

With this patch, we can now see its WiFi chip:
bcma: bus0: Found chip with id 43142, rev 0x01 and package 0x08
bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x28, class 0x0)
bcma: bus0: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x21, class 0x0)
bcma: bus0: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x16, class 0x0)
bcma: bus0: Core 3 found: UNKNOWN (manuf 0x43B, id 0x368, rev 0x00, class 0x0)
bcma: bus0: Found rev 15 PMU (capabilities 0x518C5E0F)
bcma: bus0: SPROM offset 0x840
bcma: bus0: Found SPROM revision 10
bcma: bus0: Workarounds unknown or not needed for device 0xA886
bcma: bus0: Bus registered

But it not yet supported by brcmsmac so it won't work for now:
brcmsmac bcma0:1: brcms_b_attach wl0: vendor 0x14e4 device 0x4365
brcmsmac: unknown device id 4365
