usb: sunxi: access ahb_reset0_cfg in CCM using its offset

struct sunxi_ccm_reg doesn't have ahb_reset0_cfg on sun4i and sun5i,
thus compilation fails with:

drivers/usb/host/ohci-sunxi.c:96:26: error: 'struct sunxi_ccm_reg' has
no member named 'ahb_reset0_cfg'

Access this reg using its offset to fix this issue.

Fixes commit 1ed9c1118 ("usb: sunxi: ehci: get rid of ifdefs")
and commit 56830cee3 ("usb: sunxi: ohci: get rid of ifdefs")
