In order to circumvent CCU NOC issue in Agilex5, it is recommended
to disable cache allocation for reads. This prevents hang issues
caused by CCP (Common Cache Pipe) Fill Done FIFO overflow.

Bit 3 of the seq2core register is no longer set to indicate
calibration completion. Instead, added polling of the seq2core
register until it reads 0b00000111, signaling that the Nios
processor has started the calibration process.

Some legacy USB mass storage devices during connection were
observed to have debounce issues. Hence, increasing the default
USB Hub debounce timeout value to handle this issue for devices
connected to Agilex5 boards.

Secure Device Manager(SDM) has only 512MB window address space to
HPS over PSI BE link. The default access range is 0x0 to 0x1FFFFFFF.
To allow SDM accessing the address space more than 512MB, SMMU has
to be setup for address translation.

A conditional check is added to not allow the fpga reconfiguration
for any bitstream data where address exceeds 512MB, unless
PSI BE link address translation is setup in SMMU.

Remove the current CONFIG_SYS_BOOTM_LEN in N5X VAB defconfig.
Previously, the size was set to 32MB, but due to larger kernel image,
64MB size is required. This 64MB configuration has been set as
default in the Kconfig.
