[Buildroot] [PATCH V4 02/11] arch/csky: Change DSP to VDSP for -mcpu

[guoren at kernel.org <guoren@kernel.org>]

From: Guo Ren <ren_guo@c-sky.com>

DSP extention is no longer used for C-SKY gcc and use VDSP instead of
DSP.

VDSP is C-SKY enhanced extension instruction set for SIMD, AI and DSP
operation. It could be supported by abiv2 (ck807, ck810, ck860).
