Issue Description:
PSDK RTOS OSPI 133MHz DTR PHY tuning algorithm "nor_spi_phy_tune.c" is unable to find RxMin for a given Tx Window between the search range from 0-10. This can result in a failed OSPI boot sequence.

E.g.

#Finding Rx Min for given Tx window.

1.For each discrete TxDll in TxDll_Low_Window.

a. For each read delay between 1-4:

i. For RxDll b/w 0-10.

I. If read returns success, mark TxDll, rdDelay and RxDll and break.

RxDllMinLow = marked_rx_dll in 1.a.i.I.

Resolution Description:
For a given txDll, updated search range for rxDll from 0-10 to 0-40.
