DA1469x dma driver initialization fails

[ydamigos]

Describe the bug

DMA driver initialization fails when PM_DEVICE is set:

ASSERTION FAIL [cnt >= 1] @ WEST_TOPDIR/zephyr/subsys/pm/policy.c:319
	Unbalanced state lock get/put
E: r0/a1:  0x00000004  r1/a2:  0x0000013f  r2/a3:  0x20000950

E:  xpsr:  0x29000000
E: Faulting instruction address (r15/pc): 0x16009dc2
E: >>> ZEPHYR FATAL ERROR 4: Kernel panic on CPU 0
E: Current thread: 0x20000950 (main)

To Reproduce

west build -b da1469x_dk_pro -p always tests/drivers/dma/chan_blen_transfer
west flash
See dma driver assertion.
