i3c: don't fail if GETHDRCAP is unsupported

'I3C_BCR_HDR_CAP' is still spec v1.0 and has been renamed to 'advanced
capabilities' in v1.1 onwards. The ST pressure sensor LPS22DF does not
have HDR, but has the 'advanced cap' bit set. The core still wants to
get additional information using the CCC 'GETHDRCAP' (or GETCAPS in v1.1
onwards). Not all controllers support this CCC and will notify the upper
layers about it. For instantiating the device, we can ignore this
unsupported CCC as standard communication will work. Without this patch,
the device will not be instantiated at all.
