uniphier: increase BL33 max size and GZIP temporary buffer size

The current BL33 size is large enough for U-Boot, but we need to
increase the limit to use other boot loaders such as edk2.

Increase the buffer size used for GZIP decompression too.

 BL33 max size (UNIPHIER_BL33_MAX_SIZE):  1MB -> 8MB
 GZIP buffer (UNIPHIER_IMAGE_BUF_SIZE):   1MB -> 8MB

Increasing the block buffer size (UNIPHIER_BLOCK_BUF_SIZE) is not
required, but I increased it too to make it work more efficiently.
