drm/amdgpu: Bound GPIO I2C table entry count from VBIOS
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Bound GPIO I2C table entry count from VBIOS Reject undersized tables and cap the derived entry count to AMDGPU_MAX_I2C_BUS so we do not overrun adev->i2c_bus[] or walk an absurd number of entries on corrupt size fields.
