Subject: [PATCH v1] arm: pxa: fix DT node name for PXA27X usb

Without this patch I am getting an error:
---8<---
[   15.709742] ohci-pxa27x: OHCI PXA27x/PXA3x driver
[   15.737150] pxa27x-ohci: probe of 4c000000.ohci failed with error -2
---8<---

The error is generated in drivers/usb/host/ohci-pxa27x.c at line 441:
---8<---
441:	usb_clk = devm_clk_get(&pdev->dev, NULL);
442:	if (IS_ERR(usb_clk))
443:		return PTR_ERR(usb_clk);
---8<---

The error is caused by different names for the same DT node in pxa2xx.dtsi
and pxa27x.dtsi.
