[SRU][Jammy:linux-intel-iotg][PATCH v2 03/10] iio: accel: adxl345: Get rid of name parameter in adxl345_core_probe()

[Jian Hui Lee]

From: Andy Shevchenko <andriy.shevchenko at linux.intel.com>

BugLink: https://launchpad.net/bugs/1962674

As a preparation to switch to use device properties, get rid of name
parameter in adxl345_core_probe(). Instead, choose it based on the type.
