qt5/qt5base: Fix build on MIPS without DSP support

The qt_memfill32_asm_mips_dsp function is only declared if
QT_COMPILER_SUPPORTS_MIPS_DSP is defined, so we can't reference it
unless the same macro is defined.

Backporting an upstream patch to fix this issue.

This is the error message:

qt-everywhere-enterprise-src-5.4.0-alpha/qtbase/src/gui/painting/qdrawhelper.cpp:
In function 'void qInitDrawhelperAsm()':
qt-everywhere-enterprise-src-5.4.0-alpha/qtbase/src/gui/painting/qdrawhelper.cpp:6843:
error: 'qt_memfill32_asm_mips_dsp' was not declared in this scope
