The content of bd71815_regulators is never changed, no need to duplicate
it, thus remove descs[BD71815_REGULATOR_CNT].
The *regmap, *dev and *rdev[BD71815_REGULATOR_CNT] are not really needed.
The *gps is unused.

Thus the struct bd71815_pmic can be removed.

The MT6359_BUCK and MT6359_LDO_LINEAR macros setup both
linear settings (min_uV, uV_step, linear_min_sel) and linar_range
(linear_ranges, n_linear_ranges) settings.
All the linear range tables actually only has one entry.
Let's simplify it by using linear instead of linear range.

The linear_min_sel setting is 0 for all cases, remove it
from the macros.

For rk3399pro boards the tcs4526 regulator supports the vdd_gpu
regulator. The tcs4526 regulator has a chip id of <0>.
Add the compatibile tcs,tcs4526

without this patch, the dmesg output is:
  fan53555-regulator 0-0010: Chip ID 0 not supported!
  fan53555-regulator 0-0010: Failed to setup device!
  fan53555-regulator: probe of 0-0010 failed with error -22
with this patch, the dmesg output is:

The regulators are described as:
- Dedicated power management IC TCS4525
- Lithium battery protection chip TCS4526

This has been tested with a Radxa Rock Pi N10.

The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.
