[U-Boot] [PATCH v2 2/2] spi: ti_qspi: Remove unnecessary udelay for AM437x

[Vignesh R]

This udelay() was added as an HACK and is no longer required. All
read/write/erase operations work fine even without this delay. Hence,
remove the udelay() call.

Tested read/write/erase operation on AM437x SK. Also tested QSPI Boot.
