drm: mali-dp: Enable Global SE interrupts mask for DP500

Browse Source 
[ Upstream commit 89610dc2c235e7b02bb9fba0ce247e12d4dde7cd ]

In the situation that DE and SE aren’t shared the same interrupt number,
the Global SE interrupts mask bit MASK_IRQ_EN in MASKIRQ must be set, or
else other mask bits will not work and no SE interrupt will occur. This
patch enables MASK_IRQ_EN for SE to fix this problem.
