CVE-2025-22049 LoongArch: Increase ARCH_DMA_MINALIGN up to 16

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Increase ARCHDMAMINALIGN up to 16 ARCHDMAMINALIGN is 1 by default, but some LoongArch-specific devices such as APBDMA require 16 bytes alignment. When the data buffer length is too small, the hardware may make an error...
