ARM: dts: imx53: drop fallback compatible "dlg,da9052"
The "dlg,da9053-aa" compatible string is not compatible with "dlg,da9052".
DA9052 vs DA9053-AA Differences (from da9052-regulator.c)
1. BUCK4 Voltage Range (only regulator table difference)
DA9052 BUCK4 DA9053-AA BUCK4
Min voltage 1800 mV 950 mV
Max voltage 3600 mV 2525 mV
Step size 50 mV 25 mV
DA9052 BUCK4 also has a non-linear voltage mapping above 3V (step increases
to 100 mV for selector >= 24). DA9053-AA BUCK4 has no such special mapping.
2. BUCK Current Limits
Level DA9052 (all BUCKs) DA9053-AA BUCK1 DA9053-AA BUCK2/3/4
0 700 mA 1600 mA 800 mA
1 800 mA 2000 mA 1000 mA
2 1000 mA 2400 mA 1200 mA
3 1200 mA 3000 mA 1500 mA
DA9053-AA BUCK1 supports up to 3A (vs 1.2A on DA9052).
Drop the fallback compatible to fix the following CHECK_DTBS warning:
dialog@48 (dlg,da9053-aa): compatible: ['dlg,da9053-aa', 'dlg,da9052'] is too long
