phy: sun4i-usb: update array size
With gcc 12.3.0, when this file is built, we get errors such as:
drivers/phy/allwinner/phy-sun4i-usb.c: In function ‘sun4i_usb_phy_probe’:
drivers/phy/allwinner/phy-sun4i-usb.c:790:52: error: ‘_vbus’ directive output may be truncated writing 5 bytes into a region of size between 2 and 12 [-Werror=format-truncation=]
790 | snprintf(name, sizeof(name), "usb%d_vbus", i);
| ^~~~~
drivers/phy/allwinner/phy-sun4i-usb.c:790:17: note: ‘snprintf’ output between 10 and 20 bytes into a destination of size 16
790 | snprintf(name, sizeof(name), "usb%d_vbus", i);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Because of the possible value of 'i', this can't be an issue in real world
application, but in order to have "make W=1" work correctly, give more
space for 'name'.
