Abinash Singh 3df63fa8f2 dma: dw-edma: Fix build warning in dw_edma_pcie_probe()

The function dw_edma_pcie_probe() in dw-edma-pcie.c triggered a
frame size warning:
ld.lld⚠️
  drivers/dma/dw-edma/dw-edma-pcie.c:162:0: stack frame size (1040) exceeds limit (1024) in function 'dw_edma_pcie_probe'

This patch reduces the stack usage by dynamically allocating the
`vsec_data` structure using kmalloc(), rather than placing it on
the stack. This eliminates the overflow warning and improves kernel
robustness.
