Subject: [PATCH 0/3] Fix build issue when CONFIG_MODULES is not set

When CONFIG_MODULES is not defined, 'adap->owner->name' used in amd_isp4 platform
driver will not be valid and is resulting in build failures.

../drivers/platform/x86/amd/amd_isp4.c: In function 'is_isp_i2c_adapter':
../drivers/platform/x86/amd/amd_isp4.c:154:35: error: invalid use of undefined type 'struct module'
  154 |         return !strcmp(adap->owner->name, "i2c_designware_amdisp");
      |                                   ^~

To fix this issue, I need to make changes both in platform and i2c driver modules.

* In the amd_isp4 x86/platform driver, replace 'adap->owner->name' with 'adap->name', this removes
the hard dependency on 'struct module'.
* In i2c amdisp driver, initialize unique name to i2c adapter and also make a change in
i2c-designware-common to avoid overwriting with generic name when adap->name[] is already set.

Thanks,
Pratap
