power: qpnp-fg-gen4: Add 1 second delay after loading profile on PM8150B v1

For the DMA workaround in PM8150B v1, ALG active signal is polled
before DMA grant request is placed for SRAM access. ALG active is
asserted low within the expected time mostly. However, after the
profile is loaded by FG driver, an additional delay of 1 FG cycle
(1 second) is required. Add it.
