Subject: [PATCH net-next 05/33] can: esd_usb: Use consistent prefixes for macros

From: Frank Jungclaus <frank.jungclaus@....eu>

Add the consistent prefix ESD_USB_ to all macros defined within
esd_usb.c.
For macros specific to esd CAN-USB/2 use ESD_USB_2_ as prefix.
For macros specific to esd CAN-USB/Micro use ESD_USB_M_ as prefix.
Change the macro ESD_USB_3_SAMPLES to ESD_USB_TRIPLE_SAMPLES to not
mix up with the prefix ESD_USB_3_ which will be introduced for the
CAN-USB/3 device.
